arm64 festive updates for 4.21
In the end, we ended up with quite a lot more than I expected: - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and kernel-side support to come later) - Support for per-thread stack canaries, pending an update to GCC that is currently undergoing review - Support for kexec_file_load(), which permits secure boot of a kexec payload but also happens to improve the performance of kexec dramatically because we can avoid the sucky purgatory code from userspace. Kdump will come later (requires updates to libfdt). - Optimisation of our dynamic CPU feature framework, so that all detected features are enabled via a single stop_machine() invocation - KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that they can benefit from global TLB entries when KASLR is not in use - 52-bit virtual addressing for userspace (kernel remains 48-bit) - Patch in LSE atomics for per-cpu atomic operations - Custom preempt.h implementation to avoid unconditional calls to preempt_schedule() from preempt_enable() - Support for the new 'SB' Speculation Barrier instruction - Vectorised implementation of XOR checksumming and CRC32 optimisations - Workaround for Cortex-A76 erratum #1165522 - Improved compatibility with Clang/LLD - Support for TX2 system PMUS for profiling the L3 cache and DMC - Reflect read-only permissions in the linear map by default - Ensure MMIO reads are ordered with subsequent calls to Xdelay() - Initial support for memory hotplug - Tweak the threshold when we invalidate the TLB by-ASID, so that mremap() performance is improved for ranges spanning multiple PMDs. - Minor refactoring and cleanups -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABCgAGBQJcE4TmAAoJELescNyEwWM0Nr0H/iaU7/wQSzHyNXtZoImyKTul Blu2ga4/EqUrTU7AVVfmkl/3NBILWlgQVpY6tH6EfXQuvnxqD7CizbHyLdyO+z0S B5PsFUH2GLMNAi48AUNqGqkgb2knFbg+T+9IimijDBkKg1G/KhQnRg6bXX32mLJv Une8oshUPBVJMsHN1AcQknzKariuoE3u0SgJ+eOZ9yA2ZwKxP4yy1SkDt3xQrtI0 lojeRjxcyjTP1oGRNZC+BWUtGOT35p7y6cGTnBd/4TlqBGz5wVAJUcdoxnZ6JYVR O8+ob9zU+4I0+SKt80s7pTLqQiL9rxkKZ5joWK1pr1g9e0s5N5yoETXKFHgJYP8= =sYdt -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 festive updates from Will Deacon: "In the end, we ended up with quite a lot more than I expected: - Support for ARMv8.3 Pointer Authentication in userspace (CRIU and kernel-side support to come later) - Support for per-thread stack canaries, pending an update to GCC that is currently undergoing review - Support for kexec_file_load(), which permits secure boot of a kexec payload but also happens to improve the performance of kexec dramatically because we can avoid the sucky purgatory code from userspace.

Pull irq updates from Thomas Gleixner:
"The interrupt department provides:
Core updates:
- Better spreading to NUMA nodes in the affinity management
- Support for more than one set of interrupts to spread out to allow
separate queues for separate functionality of a single device.
- Decouple the non queue interrupts from being managed. Those are
usually general interrupts for error handling etc. and those should
never be shut down. This also a preparation to utilize the
spreading mechanism for initial spreading of non-managed interrupts
later.
- Make the single CPU target selection in the matrix allocator more
balanced so interrupts won't accumulate on single CPUs in certain
situations.
- A large spell checking patch so we don't end up fixing single typos
over and over.
Driver updates:
- A bunch of new irqchip drivers (RDA8810PL, Madera, imx-irqsteer)
- Updates for the 8MQ, F1C100s platform drivers
- A number of SPDX cleanups
- A workaround for a very broken GICv3 implementation on msm8996
which sports a botched register set.

Device properties framework updates for 4.21-rc1
- Introduce "software nodes", analogous to the DT and ACPI firmware
nodes except that they can be created by kernel code, in order to
complement fwnodes representing real firmware nodes when they are
incomplete (for example missing device properties) and to supply
the primary fwnode when the firmware lacks hardware description
for a device completely, and replace the "property_set" struct
fwnode_handle type with software nodes (Heikki Krogerus).
- Clean up the just introduced software nodes support and fix a commet
in the graph-handling code (Colin Ian King, Marco Felsch).

This round is dominated by NXP's i.MX clk drivers. We gained support for two or
three i.MX SoCs in here and that mostly means a lot of driver code and data.
Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk
drivers added in here, and then we get to the long tail of driver updates and
non-critical fixes all around, including code for vendors such as Renesas,
Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal.
Beyond the usual driver updates we have an update to make registering OF based
clk providers a little simpler when they're devices created as a child of a
device backed by a node in DT. Drivers don't have to jump through hoops to
unregister the provider upon driver removal anymore because the API does the
right thing and uses the parent device DT node.
Core:
- Make devm_of_clk_add_hw_provider() use parent dt node if necessary
- Various SPDX taggings
- Mark clk_ops const when possible
New Drivers:
- NXP i.MX7ULP SoC clock support
- NXP i.MX8QXP SoC clock support
- NXP i.MX8MQ SoC clock support
- NXP QorIQ T1023 SoC support
- Qualcomm SDM845 audio subsystem clks
- Qualcomm SDM845 GPU clck controllers
- Qualcomm QCS404 RPM clk support
- Mediatek MT7629 SoC clk controllers
- Allwinner F1c100s SoC clocks
- Allwinner H6 display engine clocks
- Amlogic GX video clocks
- Support for Amlogic meson8b CPU frequency scaling
- Amlogic Meson8b CPU post-divider clocks
Updates:
- Proper suspend/resume on VersaClock5
- Shrink code some with DEFINE_SHOW_ATTRIBUTE()
- Register fixes for Rockchip rk3188 and rk3328
- One new critical clock for Rockchip rk3188 and a fixed clock id (double used number)
- New clock id for Rockchip rk3328
- Amlogic Meson8/Meson8b video clock support
- Amlogic got a clk-input helper and used it for the axg-audio clock driver
- Sigma Delta modulation for the Allwinner A33 audio clocks
- Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs
- Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W
- Support for SDHI and USB clocks on Renesas RZ/A2
- Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas R-Car V3M
- Qualcomm MSM8998 GCC driver improvements (resets, drop unused clks, etc.)

regmap: Updates for v4.21
This has been a busy release for the regmap-irq code, there's several
new features been added, including an API cleanup for how we specify
types that affected one existing driver (gpio-max77620):
- Support for hardware that flags rising and falling edges on separate
status bits from Bartosz Golaszewski.
- Support for explicitly clearing interrupts before unmasking from
Bartosz Golaszewski.
- Support for level triggered IRQs from Matti Vaittinen.

spi: Updates for v4.21
The main thing this release has been a lot of work on the integration
with SPI NOR flashes, there's been some specific support for a while for
controller features designed to make them perform better but it's not
worked out as well as hoped so the interface has been redesigned in a
way that will hopefully do better - it's already been adopted by a
number of additional controllers so things are looking good. Otherwise
most of the work has been driver specific:
- Support for better integration with NOR flashes from Boris Brezillon
and Yogesh Narayan Gaur plus usage of it in several drivers.
- A big cleanup of the Rockchip driver from Emil Renner Berthing.
- Lots of performance improvements for bcm2835 from Lukas Wunner.
- Slave mode support for pxa2xx from Lubomir Rintel.
- Support for Macronix MXIC, Mediatek MT7629 and MT8183, NPCM PSPI,
and Renesas r8a77470.

regulator: Updates for v4.20
This has been a very busy release for the core, some fixes, one large new
feature and a big bit of refactoring to update the GPIO API:
- Support for coupled regulators from Dmitry Osipenko based on a prior
attempt by Maciej Purski, allowing us to handle situations where the
voltages on two regulators can't be too far apart from each other.
- Conversion of the GPIO support in both drivers and the core to use
GPIO descriptors rather than numbers, part of the overall project to
remove GPIO numbers.
- Support for standby mode suspend states from Andrei Stefanescu.
- New drivers for Allwinner AXP209, Cirrus Logic Lochnagar and
Microchip MPC16502.

pwm: Changes for v4.21-rc1
Not a lot going on this cycle. There's some more cleanup going on and new driver support that was not quite ready in time for v4.21-rc1, but here are a few fixes and improvements that are good to go. The Kona PWM driver can now be built on the Cygnus architecture and the i.MX driver gained support for hardware readback. Some small fixes are provided for the clks711x and lpc18xx-sct drivers. Finally, to round things off some drivers are switched to SPDX license identifiers. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEiOrDCAFJzPfAjcif3SOs138+s6EFAlwgvusZHHRoaWVycnku cmVkaW5nQGdtYWlsLmNvbQAKCRDdI6zXfz6zobXWEACgOF26QUs/Vt6n7r7XRXeL rHZwhJ44+0/wHm6MNJcj8jy7Ct0iJVBhxyK4680A0n2u1T6SxA0YZu2yVC46iNFc 52bipsZ3U8uuKHBvWhGxmYXknj1nJqKPg2yAxyJ4dD6LlJaGYJKaxZe4BH/gZ4qI WaYH88rcopfcVcrzl57IPoibiEwfN1V2WAvGkKihj1y1KN65mbUHgRFAqAA2s0u/ qdpGpqIrBEHeOZSoKuNDEADkO5xiHpO+uEcxY2xeWg0onP/X+tVHerkG28+ruwP/ PWXI3uEe9SAeEzf3YKNqCNWLLRVQ/+JU6oS6qwMjhgV5w+HppIMIUJUo1hddofL0 RvTZ3IhTpGXGCYpp1OuF51ZWZpTb56VZ4roHt20bjaYLqA6SEu0AszxELVvOYO+B kBVMwohtNYeZpuM2eGOdvZAMG55cicRa55MZzpCDMNfJZSr0CrVwnX6o5MKTuozA B21wxm9PPR/miPBmGnFegXmuqB+Uf/uWqXeGfWwwdlfS4dchOb8pBxDoO5P53Dx6 xOnfWQu0Ol1sUVLXg9l0rEJAHx1F3SncrE4WWnV+pK1NkMoz9+Ry5aVqIBOFI+Qw ImEssuM52sv93S9HXuNq6DOUwoOSwkE4HSjPneKmAA1XMQ846YB/zj2R0Ki+dZAK Zlk9HVwIOKpP0gG0tcPBOA== =ni7n -----END PGP SIGNATURE----- Merge tag 'pwm/for-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm updates from Thierry Reding: "Not a lot going on this cycle.

- Make it possible to specify a cpuidle governor from kernel
command line, add new cpuidle state sysfs attributes for
governor evaluation, and improve the "polling" idle state
handling (Rafael Wysocki).
- Fix the handling of the "required-opps" DT property in the
operating performance points (OPP) framework, improve the
integration of it with the generic power domains (genpd)
framework, improve the handling of performance states in
them and clean up the idle states vs performance states
separation in genpd (Viresh Kumar, Ulf Hansson).
- Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
a hardware engine to control CPU frequency transitions along
with DT bindings for it (Taniya Das).
- Fix an intel_pstate driver issue related to CPU offline and
update the documentation of it (Srinivas Pandruvada).
- Clean up the imx6q cpufreq driver (Anson Huang).
- Add SPDX license IDs to cpufreq schedutil governor files (Daniel
Lezcano).
- Switch over the runtime PM framework to using high-res timers
for device autosuspend to allow the control of it to be more
precise (Vincent Guittot).
- Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
don't prevent the system from reaching the target low-power state
and simplify the suspend-to-idle handling on ACPI platforms
without full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
- Add system-wide suspend and resume support to the devfreq

sound updates for 4.21
There are no intensive changes in both ALSA and ASoC core parts while
rather most of changes are a bunch of driver fixes and updates.
A large diff pattern appears in ASoC TI part which now merges both
OMAP and DaVinci stuff, but the rest spreads allover the places.
Note that this pull request includes also some updates for LED trigger
and platform drivers for mute LEDs, appearing in the diffstat as well.
Some highlights:
ASoC:
- Preparatory work for merging the audio-graph and audio-graph-scu
cards
- A merge of TI OMAP and DaVinci directories, as both product lines
get merged together. Also including a few architecture changes as
well.
- Major cleanups of the Maxim MAX9867 driver
- Small fixes for tablets & co with Intel BYT/CHT chips
- Lots of rsnd updates as usual
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
controllers
HD-audio:
- Introduce audio-mute LED trigger for replacing the former hackish
dynamic binding
- Huawei WMI hotkey and mute LED support
- Refactoring of PM code and display power controls
- Headset button support in the generic jack code
- A few updates for Tegra
- Fixups for HP EliteBook and ASUS UX391UA
- Lots of updates for Intel ASoC HD-audio, including the improved DSP
detection and the fallback binding from ASoC SST to legacy HD-audio
controller drivers
Others:
- Updates for FireWire TASCAM and Fireface devices, some other fixes
- A few potential Spectre v1 fixes that are all trivial

platform-drivers-x86 for v4.21-1
The USB Power Delivery discrete components now can be enumerated by i2c-multi-instantiate driver via several resources under single ACPI device node (ACPI ID is INT3515). Touchscreen support is added for the Mediacom Flexbook Edge 11. Mellanox driver got fixed due to updates in their firmware. The power management stub driver for AtomISP v2 is fixed in order to support Intel Baytrail SoCs where same quirk is needed for S0ix to work. Special key handling has been fixed for Favorites hotkey on Thinkpad, and Screen LOCK on ASUS. Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been updated to support this. Few cleanups related to debugfs have been made in Intel IPS and Intel PMC drivers. Besides that Intel PMC has been extended to show more detailed information about Latency Tolerance. The following is an automated git shortlog grouped by driver: ACPI / scan: - Create platform device for INT3515 ACPI nodes Add the VLV ISP PCI ID to atomisp2_pm: - Add the VLV ISP PCI ID to atomisp2_pm asus-nb-wmi: - Drop mapping of 0x33 and 0x34 scan codes - Map 0x35 to KEY_SCREENLOCK asus-wmi: - Tell the EC the OS will handle the display off hotkey dell-laptop: - Mark expected switch fall-throughs Documentation/ABI: - Add new attribute for mlxreg-io sysfs interfaces Fix config space access for intel_atomisp2_pm: - Fix config space access for intel_atomisp2_pm i2c: - acpi: Introduce i2c_acpi_get_i2c_resource() helper - acpi: Use ACPI_FAILURE instead of !ACPI_SUCCESS - acpi: Return error pointers from i2c_acpi_new_device() i2c-multi-instantiate: - Allow to have same slaves - Introduce IOAPIC IRQ support - Distinguish IRQ resource type - Count I2cSerialBus() resources - Get rid of obsolete conditional - Defer probe when no adapter found - Accept errors of i2c_acpi_new_device() ideapad-laptop: - Add Yoga 2 13 to no_hw_rfkill list iio: - inv_mpu6050: Use i2c_acpi_get_i2c_resource() helper intel_cht_int33fe: - Get rid of obsolete conditional - Accept errors of i2c_acpi_new_device() - Remove duplicate NULL check intel_ips: - Convert to use DEFINE_SHOW_ATTRIBUTE macro - Remove never happen condition - NULL check before some freeing functions is not needed - remove unnecessary checks in ips_debugfs_init intel_pmc_core: - convert to DEFINE_SHOW_ATTRIBUTE - Decode Snoop / Non Snoop LTR - Fix LTR IGNORE Max offset - Show Latency Tolerance info intel_telemetry: - convert to DEFINE_SHOW_ATTRIBUTE mlx-platform: - Convert to use SPDX identifier - Allow mlxreg-io driver activation for new systems - Fix LED configuration - Fix tachometer registers - Rename new systems product names - Add definitions for new registers thinkpad_acpi: - Cleanup quirks macros - Change the keymap for Favorites hotkey touchscreen_dmi: - Add info for the Mediacom Flexbook Edge 11 -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEqaflIX74DDDzMJJtb7wzTHR8rCgFAlwRE+sACgkQb7wzTHR8 rCi7URAAgpfdsHUkj3PdFmp5o3LHCD0m5Z9A6yAJrXyhCDRRkAMaGYyRe4vg3qE1 GBA6MbMyOrtW/LqvaQAajeMmDINl1Mz/5OIVCIwJUPnKk8K7Yy93pH5vKecUPX8q ihItKmJIPdaqxH2LXrx6sh3Ob3QrVrcpfpW6109WM8auYB+BiNOhxejBZ4jvMiRd 9dG657gx64Y6Ot5kjGKpdblFrA930sA5kAiMFiCcjNP9S7xLhgfyZiPMSP48gUWb OiqoJMsomamF8qxZsZzfRblZpOlFahuW51D2vZgHb7N6fA0qW1c3twdSoivQfTHa KA+OuMgJ52vI8JDgUKj55LB88Pn5iFtmDsNodgQ25cBLgBkzKJQU9MfoK8QafvlV OTjmGL+ENK4VufDwMEgOMlXdihVewOrQ3kzOm7JQgIlOSWE7l9BSa2CK0vSM9Jha nfjjc5LowJaWA+QUrmx29VrRGmSYfrGhquGV/3U+TPafc5blpiqWTGxIkhaNFhKx 0yk/vzggGsIlvnYU2+zaJW8LAhLcb4R6ATEZMurZQdZlQefs+5oAEPSvOZ5gYdLX PWj3swTMkIp7FKjGm7532T83v5lJyO9cxSV/3aIqzkdWNqMoYDDuNU8wCzTTBv5m EoKQO+H2WCnlm5bgWQ82gjVDKmS63eDlT4WgYxm60OZ1ONuAwIo= =kYH6 -----END PGP SIGNATURE----- Merge tag 'platform-drivers-x86-v4.21-1' of git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver updates from Andy Shevchenko: - The USB Power Delivery discrete components now can be enumerated by i2c-multi-instantiate driver via several resources under single ACPI device node (ACPI ID is INT3515). - Touchscreen support is added for the Mediacom Flexbook Edge 11. - Mellanox driver got fixed due to updates in their firmware. - The power management stub driver for AtomISP v2 is fixed in order to support Intel Baytrail SoCs where same quirk is needed for S0ix to work. - Special key handling has been fixed for Favorites hotkey on Thinkpad, and Screen LOCK on ASUS. - Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been updated to support this. - Few cleanups related to debugfs have been made in Intel IPS and Intel PMC drivers.

pwm: imx: Add ipg clock operation
i.MX PWM module's ipg_clk_s is for PWM register access, on most of i.MX
SoCs, this ipg_clk_s is from system ipg clock or perclk which is always
enabled, but on i.MX7D, the ipg_clk_s is from PWM1_CLK_ROOT which is
controlled by CCGR132, that means the CCGR132 MUST be enabled first
before accessing PWM registers on i.MX7D. This patch adds ipg clock
operation to make sure register access successfully on i.MX7D and it
fixes Linux kernel boot up hang during PWM driver probe.

SCSI fixes on 20181221
This is two simple target fixes and one discard related I/O starvation problem in sd. The discard problem occurs because the discard page doesn't have a mempool backing so if the allocation fails due to memory pressure, we then lose the forward progress we require if the writeout is on the same device.

While playing with gigantic hugepages and memory_hotplug, I triggered the following #PF when "cat memoryX/removable": BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 #PF error: [normal kernel read fault] PGD 0 P4D 0 Oops: 0000 [#1] SMP PTI CPU: 1 PID: 1481 Comm: cat Tainted: G E 4.20.0-rc6-mm1-1-default+ #18 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.0.0-prebuilt.qemu-project.org 04/01/2014 RIP: 0010:has_unmovable_pages+0x154/0x210 Call Trace: is_mem_section_removable+0x7d/0x100 removable_show+0x90/0xb0 dev_attr_show+0x1c/0x50 sysfs_kf_seq_show+0xca/0x1b0 seq_read+0x133/0x380 __vfs_read+0x26/0x180 vfs_read+0x89/0x140 ksys_read+0x42/0x90 do_syscall_64+0x5b/0x180 entry_SYSCALL_64_after_hwframe+0x44/0xa9 The reason is we do not pass the Head to page_hstate(), and so, the call to compound_order() in page_hstate() returns 0, so we end up checking all hstates's size to match PAGE_SIZE. Obviously, we do not find any hstate matching that size, and we return NULL. Then, we dereference that NULL pointer in hugepage_migration_supported() and we got the #PF from above. Fix that by getting the head page before calling page_hstate(). Also, since gigantic pages span several pageblocks, re-adjust the logic for skipping pages. While are it, we can also get rid of the round_up().

mm: thp: fix flags for pmd migration when split
When splitting a huge migrating PMD, we'll transfer all the existing PMD bits and apply them again onto the small PTEs. However we are fetching the bits unconditionally via pmd_soft_dirty(), pmd_write() or pmd_yound() while actually they don't make sense at all when it's a migration entry. Fix them up. Since at it, drop the ifdef together as not needed. Note that if my understanding is correct about the problem then if without the patch there is chance to lose some of the dirty bits in the migrating pmd pages (on x86_64 we're fetching bit 11 which is part of swap offset instead of bit 2) and it could potentially corrupt the memory of an userspace program which depends on the dirty bit.

mm, memory_hotplug: initialize struct pages for the full memory section
If memory end is not aligned with the sparse memory section boundary, the mapping of such a section is only partly initialized. This may lead to VM_BUG_ON due to uninitialized struct page access from is_mem_section_removable() or test_pages_in_a_zone() function triggered by memory_hotplug sysfs handlers: Here are the the panic examples: CONFIG_DEBUG_VM=y CONFIG_DEBUG_VM_PGFLAGS=y kernel parameter mem=2050M -------------------------- page:000003d082008000 is uninitialized and poisoned page dumped because: VM_BUG_ON_PAGE(PagePoisoned(p)) Call Trace: ( test_pages_in_a_zone+0xde/0x160) show_valid_zones+0x5c/0x190 dev_attr_show+0x34/0x70 sysfs_kf_seq_show+0xc8/0x148 seq_read+0x204/0x480 __vfs_read+0x32/0x178 vfs_read+0x82/0x138 ksys_read+0x5a/0xb0 system_call+0xdc/0x2d8 Last Breaking-Event-Address: test_pages_in_a_zone+0xde/0x160 Kernel panic - not syncing: Fatal exception: panic_on_oops kernel parameter mem=3075M -------------------------- page:000003d08300c000 is uninitialized and poisoned page dumped because: VM_BUG_ON_PAGE(PagePoisoned(p)) Call Trace: ( is_mem_section_removable+0xb4/0x190) show_mem_removable+0x9a/0xd8 dev_attr_show+0x34/0x70 sysfs_kf_seq_show+0xc8/0x148 seq_read+0x204/0x480 __vfs_read+0x32/0x178 vfs_read+0x82/0x138 ksys_read+0x5a/0xb0 system_call+0xdc/0x2d8 Last Breaking-Event-Address: is_mem_section_removable+0xb4/0x190 Kernel panic - not syncing: Fatal exception: panic_on_oops Fix the problem by initializing the last memory section of each zone in memmap_init_zone() till the very end, even if it goes beyond the zone end.

serial/sunsu: fix refcount leak
The function of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. su_get_type() doesn't do that. The match node are used as an identifier to compare against the current node, so we can directly drop the refcount after getting the node from the path as it is not used as pointer. Fix this by use a single variable and drop the refcount right after of_find_node_by_path(). Signed-off-by: Yangtao Li <tiny.windzz@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

tls: Do not call sk_memcopy_from_iter with zero length
In some conditions e.g. when tls_clone_plaintext_msg() returns -ENOSPC,
the number of bytes to be copied using subsequent function
sk_msg_memcopy_from_iter() becomes zero. This causes function
sk_msg_memcopy_from_iter() to fail which in turn causes tls_sw_sendmsg()
to return failure. To prevent it, do not call sk_msg_memcopy_from_iter()
when number of bytes to copy (indicated by 'try_to_copy') is zero.
