Device managed panel bridge wrappers are created by calling to
drm_panel_bridge_add_typed() and registering a release handler for
clean-up when the device gets unbound.
Since the memory for this bridge is also managed and linked to the panel
device, the release function should not try to free that memory.
Moreover, the call to devm_kfree() inside drm_panel_bridge_remove() will
fail in this case and emit a warning because the panel bridge resource
is no longer on the device resources list (it has been removed from
there before the call to release handlers).

The frame pointer unwinder relies on a standard layout of the stack
frame, consisting of (in downward order)
Calling frame:
PC <---------+
LR |
SP |
FP |
.. locals .. |
Callee frame: |
PC |
LR |
SP |
FP ----------+
where after storing its previous value on the stack, FP is made to point
at the location of PC in the callee stack frame, using the canonical
prologue:
mov ip, sp
stmdb sp!, {fp, ip, lr, pc}
sub fp, ip, #4
The ftrace code assumes that this activation record is pushed first, and
that any stack space for locals is allocated below this. Strict
adherence to this would imply that the caller's value of SP at the time
of the function call can always be obtained by adding 4 to FP (which
points to PC in the callee frame).
However, recent versions of GCC appear to deviate from this rule, and so
the only reliable way to obtain the caller's value of SP is to read it
from the activation record. Since this involves a read from memory
rather than simple arithmetic, we need to use the uaccess API here which
protects against inadvertent data aborts resulting from attempts to
dereference bogus FP values.
The plain uaccess API is ftrace instrumented itself, so to avoid
unbounded recursion, use the __get_kernel_nofault() primitive directly.

When xfs_log_sb writes super block to disk, b_fdblocks is fetched from
m_fdblocks without any lock. As m_fdblocks can experience a positive ->
negative -> positive changing when the FS reaches fullness (see
xfs_mod_fdblocks). So there is a chance that sb_fdblocks is negative, and
because sb_fdblocks is type of unsigned long long, it reads super big.
And sb_fdblocks being bigger than sb_dblocks is a problem during log
recovery, xfs_validate_sb_write() complains.
Fix:
As sb_fdblocks will be re-calculated during mount when lazysbcount is
enabled, We just need to make xfs_validate_sb_write() happy -- make sure
sb_fdblocks is not nenative. This patch also takes care of other percpu
counters in xfs_log_sb.

When reading EDID fails and driver reports no modes available, the DRM
core adds an artificial 1024x786 mode to the connector. Unfortunately
some variants of the Exynos HDMI (like the one in Exynos4 SoCs) are not
able to drive such mode, so report a safe 640x480 mode instead of nothing
in case of the EDID reading failure.
This fixes the following issue observed on Trats2 board since commit

Commit 070246e467 ("net: stmmac: Fix for mismatched host/device DMA
address width") added support in the stmmac driver for platform drivers
to indicate the host DMA width, but left it up to authors of the
specific platforms to indicate if their width differed from the addr64
register read from the MAC itself.
Qualcomm's EMAC4 integration supports only up to 36 bit width (as
opposed to the addr64 register indicating 40 bit width). Let's indicate
that in the platform driver to avoid a scenario where the driver will
allocate descriptors of size that is supported by the CPU which in our
case is 36 bit, but as the addr64 register is still capable of 40 bits
the device will use two descriptors as one address.

A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.
This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.
As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.
This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

In lio_vf_rep_copy_packet() pg_info->page is compared to a NULL value,
but then it is unconditionally passed to skb_add_rx_frag() which looks
strange and could lead to null pointer dereference.
lio_vf_rep_copy_packet() call trace looks like:
octeon_droq_process_packets
octeon_droq_fast_process_packets
octeon_droq_dispatch_pkt
octeon_create_recv_info
...search in the dispatch_list...
->disp_fn(rdisp->rinfo, ...)
lio_vf_rep_pkt_recv(struct octeon_recv_info *recv_info, ...)
In this path there is no code which sets pg_info->page to NULL.
So this check looks unneeded and doesn't solve potential problem.
But I guess the author had reason to add a check and I have no such card
and can't do real test.
In addition, the code in the function liquidio_push_packet() in
liquidio/lio_core.c does exactly the same.
Based on this, I consider the most acceptable compromise solution to
adjust this issue by moving skb_add_rx_frag() into conditional scope.

It is reported that commit 9502108876 ("thermal: core: Drop
trips_disabled bitmask") causes the maximum frequency of CPUs to drop
further down with every system sleep-wake cycle on Intel Core i7-4710HQ.
This turns out to be due to a trip point whose temperature is equal to 0
degrees Celsius which is acted on every time the system wakes from sleep.
Before commit 9502108876 this trip point would be disabled wia the
trips_disabled bitmask, but now it is treated as a valid one.
Since ACPI thermal control is generally about protection against
overheating, trip points with temperature of 0 centigrade or below are
not particularly useful there, so initialize them all as invalid which
fixes the problem at hand.

It is reported that commit 31a0fa0019 ("thermal/debugfs: Pass cooling
device state to thermal_debug_cdev_add()") causes the ACPI fan driver
to fail probing on some systems which turns out to be due to the _FST
control method returning an invalid value until _FSL is first evaluated
for the given fan. If this happens, the .get_cur_state() cooling device
callback returns an error and __thermal_cooling_device_register() fails
as uses that callback after commit 31a0fa0019.
Arguably, _FST should not return an invalid value even if it is
evaluated before _FSL, so this may be regarded as a platform firmware
issue, but at the same time it is not a good enough reason for failing
the cooling device registration where the initial cooling device state
is only needed to initialize a thermal debug facility.
Accordingly, modify __thermal_cooling_device_register() to avoid
calling thermal_debug_cdev_add() instead of returning an error if the
initial .get_cur_state() callback invocation fails.

The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).
The reset line is also wired so that it can be left deasserted when the
supply is off.
This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).
Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.
Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.
