ae62cf5eb2 staging: greybus: loopback_test: fix potential path truncations
Newer GCC warns about possible truncations of two generated path names as
we're concatenating the configurable sysfs and debugfs path prefixes
with a filename and placing the results in buffers of the same size as
the maximum length of the prefixes.

	snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id);

	snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/",
		 t->sysfs_prefix, d->name);

	snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s",
		 t->debugfs_prefix, d->name);

Fix this by separating the maximum path length from the maximum prefix
length and reducing the latter enough to fit the generated strings.

Note that we also need to reduce the device-name buffer size as GCC
isn't smart enough to figure out that we ever only used MAX_STR_LEN
bytes of it.

f160238348 staging: greybus: loopback_test: fix potential path truncation
Newer GCC warns about a possible truncation of a generated sysfs path
name as we're concatenating a directory path with a file name and
placing the result in a buffer that is half the size of the maximum
length of the directory path (which is user controlled).

loopback_test.c: In function 'open_poll_files':

Fix this by making sure the buffer is large enough the concatenated

SAMA5D2x doesn't drive CMD line if GPIO is used as CD line (at least
SAMA5D27 doesn't). Fix this by forcing card-detect in the module

18b587b45c mmc: sdhci-cadence: set SDHCI_QUIRK2_PRESET_VALUE_BROKEN for UniPhier
The SDHCI_PRESET_FOR_* registers are not set for the UniPhier platform
integration. (They are all read as zeros).

Set the SDHCI_QUIRK2_PRESET_VALUE_BROKEN quirk flag. Otherwise, the
High Speed DDR mode on the eMMC controller (MMC_TIMING_MMC_DDR52)
would not work.

I split the platform data to give no impact to other platforms,
although the UniPhier platform is currently only the upstream user
of this IP.

The SDHCI_QUIRK2_PRESET_VALUE_BROKEN flag is set if the compatible
string matches to "socionext,uniphier-sd4hc".

84d49b3d08 mmc: sdhci-acpi: Switch signal voltage back to 3.3V on suspend on external microSD on Lenovo Miix 320
Based on a sample of 7 DSDTs from Cherry Trail devices using an AXP288
PMIC depending on the design one of 2 possible LDOs on the PMIC is used
for the MMC signalling voltage, either DLDO3 or GPIO1LDO (GPIO1 pin in
low noise LDO mode).

The Lenovo Miix 320-10ICR uses GPIO1LDO in the SHC1 ACPI device's DSM
methods to set 3.3 or 1.8 signalling voltage and this appears to work
as advertised, so presumably the device is actually using GPIO1LDO for
the external microSD signalling voltage.

But this device has a bug in the _PS0 method of the SHC1 ACPI device,
the DSM remembers the last set signalling voltage and the _PS0 restores
this after a (runtime) suspend-resume cycle, but it "restores" the voltage
on DLDO3 instead of setting it on GPIO1LDO as the DSM method does. DLDO3
is used for the LCD and setting it to 1.8V causes the LCD to go black.

This commit works around this issue by calling the Intel DSM to reset the
signal voltage to 3.3V after the host has been runtime suspended.
This will make the _PS0 method reprogram the DLDO3 voltage to 3.3V, which
leaves it at its original setting fixing the LCD going black.

This commit adds and uses a DMI quirk mechanism to only trigger this
workaround on the Lenovo Miix 320 while leaving the behavior of the
driver unchanged on other devices.

785d74ec3b initramfs: restore default compression behavior
Even though INITRAMFS_SOURCE kconfig option isn't set in most of
defconfigs it is used (set) extensively by various build systems.
Commit f26661e127 ("initramfs: make initramfs compression choice
non-optional") has changed default compression mode. Previously we
compress initramfs using available compression algorithm. Now
we don't use any compression at all by default.
It significantly increases the image size in case of build system
chooses embedded initramfs. Initially I faced with this issue while
using buildroot.

As of today it's not possible to set preferred compression mode
in target defconfig as this option depends on INITRAMFS_SOURCE
being set. Modification of all build systems either doesn't look
like good option.

Let's instead rewrite initramfs compression mode choices list
the way that "INITRAMFS_COMPRESSION_NONE" will be the last option
in the list. In that case it will be chosen only if all other
options (which implements any compression) are not available.

5190044c29 modpost: move the namespace field in Module.symvers last
In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).

In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbcedf4), which is over a decade ago now.

Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.

Merge series "ALSA: compress: Add wma, alac and ape support" from Vinod Koul <vkoul@kernel.org>:
This series adds more WMA profiles and WMA decoder parameters to UAPI and
then support for these in qcom driver. It also adds FLAC and APE IDs and
decoder parameters to UAPI and then support in qcom driver

This was tested on Dragon board RB3.

Last, bump up the compressed version so that userspace can check for the
support.

Since the series touches compress uapi and asoc, it would make sense to go
thru asoc tree with acks.

Changes in v3:
 - add r-b from Srini
 - use macros for FLAC channel layout tags

Changes in v2:
 - use bitflags for wma profiles

6c3171ef76 ALSA: seq: oss: Fix running status after receiving sysex
This is a similar bug like the previous case for virmidi: the invalid
running status is kept after receiving a sysex message.

Again the fix is to clear the running status after handling the sysex.

4384f167ce ALSA: seq: virmidi: Fix running status after receiving sysex
The virmidi driver handles sysex event exceptionally in a short-cut
snd_seq_dump_var_event() call, but this missed the reset of the
running status.  As a result, it may lead to an incomplete command
right after the sysex when an event with the same running status was
queued.

Fix it by clearing the running status properly via alling
snd_midi_event_reset_decode() for that code path.

f1d96a8fcb io_uring: NULL-deref for IOSQE_{ASYNC,DRAIN}
Processing links, io_submit_sqe() prepares requests, drops sqes, and
passes them with sqe=NULL to io_queue_sqe(). There IOSQE_DRAIN and/or
IOSQE_ASYNC requests will go through the same prep, which doesn't expect
sqe=NULL and fail with NULL pointer deference.

Always do full prepare including io_alloc_async_ctx() for linked
requests, and then it can skip the second preparation.

Currently, the intel iommu debugfs directory(/sys/kernel/debug/iommu/intel)
gets populated only when DMA remapping is enabled (dmar_disabled = 0)
irrespective of whether interrupt remapping is enabled or not.

Instead, populate the intel iommu debugfs directory if any IOMMUs are

Create a quirk that allows special processing and/or

For HyperX AMP, which uses two interfaces, but only has
a capture stream in the second, this allows the capture
