Dell All In One (AIO) models released after 2017 may use a backlight
controller board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
The Dell OptiPlex 5480 AIO has an ACPI device for one of its UARTs with
the above _HID + _CID. Loading the dell-uart-backlight driver fails with
the following errors:
[ 18.261353] dell_uart_backlight serial0-0: Timed out waiting for response.
[ 18.261356] dell_uart_backlight serial0-0: error -ETIMEDOUT: getting firmware version
[ 18.261359] dell_uart_backlight serial0-0: probe with driver dell_uart_backlight failed with error -110
Indicating that there is no backlight controller board attached to
the UART, while the GPU's native backlight control method does work.
Add a quirk to use the GPU's native backlight control method on this model.

notify_hwp_interrupt() is called via sysvec_thermal() ->
smp_thermal_vector() -> intel_thermal_interrupt() in hard irq context.
For this reason it must not use a simple spin_lock that sleeps with
PREEMPT_RT enabled. So convert it to a raw spinlock.

In the s3c64xx_flush_fifo() code, the loops counter is post-decremented
in the do { } while(test && loops--) condition. This means the loops is
left at the unsigned equivalent of -1 if the loop times out. The test
after will never pass as if tests for loops == 0.

The only user (the mesa gallium driver) is already assuming explicit
synchronization and doing the export/import dance on shared BOs. The
only reason we were registering ourselves as writers on external BOs
is because Xe, which was the reference back when we developed Panthor,
was doing so. Turns out Xe was wrong, and we really want bookkeep on
all registered fences, so userspace can explicitly upgrade those to
read/write when needed.

If deferred operations are pending, we want to wait for those to
land before declaring the queue blocked on a SYNC_WAIT. We need
this to deal with the case where the sync object is signalled through
a deferred SYNC_{ADD,SET} from the same queue. If we don't do that
and the group gets scheduled out before the deferred SYNC_{SET,ADD}
is executed, we'll end up with a timeout, because no external
SYNC_{SET,ADD} will make the scheduler reconsider the group for
execution.

In case there is any sort of clock controller attached to this I2C bus
controller, for example Versaclock or even an AIC32x4 I2C codec, then
an I2C transfer triggered from the clock controller clk_ops .prepare
callback may trigger a deadlock on drivers/clk/clk.c prepare_lock mutex.
This is because the clock controller first grabs the prepare_lock mutex
and then performs the prepare operation, including its I2C access. The
I2C access resumes this I2C bus controller via .runtime_resume callback,
which calls clk_prepare_enable(), which attempts to grab the prepare_lock
mutex again and deadlocks.
Since the clock are already prepared since probe() and unprepared in
remove(), use simple clk_enable()/clk_disable() calls to enable and
disable the clock on runtime suspend and resume, to avoid hitting the
prepare_lock mutex.

Increase the timeout for checking the busy bit of the VLAN Tag register
from 10µs to 500ms. This change is necessary to accommodate scenarios

Overnight testing revealed that when EEE is active, the busy bit can
remain set for up to approximately 300ms. The new 500ms timeout provides
a safety margin.

RISC-V perf driver does not yet support PERF_TYPE_BREAKPOINT. It would
be more appropriate to return -EOPNOTSUPP or -ENOENT for this type in
pmu_sbi_event_map. Considering that other implementations return -ENOENT
for unsupported perf types, let's synchronize this behavior. Due to this
reason, a riscv bpf testcases perf_skip fail. Meanwhile, align that
behavior to the rest of proper place.

When applying padding, the buffer is not zeroed, which results in memory
disclosure. The mentioned data is observed on the wire. This patch uses
skb_put_padto() to pad Ethernet frames properly. The mentioned function
zeroes the expanded buffer.
In case the packet cannot be padded it is silently dropped. Statistics
are also not incremented. This driver does not support statistics in the
old 32-bit format or the new 64-bit format. These will be added in the
future. In its current form, the patch should be easily backported to
stable versions.
Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets
in hardware, so software padding must be applied.

the code works by coincidence with the bitwise AND, but with
CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, there's the off chance that the
condition evaluates to false, and intel_wakeref_auto() doesn't get

It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.

Like other Asus ExpertBook models the B2502CVA has its keybopard IRQ (1)
described as ActiveLow in the DSDT, which the kernel overrides to EdgeHigh
which breaks the keyboard.
Add the B2502CVA to the irq1_level_low_skip_override[] quirk table to fix
this.

Like other Asus Vivobooks, the Asus Vivobook Go E1404GA has a DSDT
describing IRQ 1 as ActiveLow, while the kernel overrides to Edge_High.
$ sudo dmesg | grep DMI:.*BIOS

There already is an entry in the irq1_level_low_skip_override[] DMI match
table for the "E1404GAB", change this to match on "E1404GA" to cover
the E1404GA model as well (DMI_MATCH() does a substring match).

Commit d2aaf1996504 ("ACPI: resource: Add DMI quirks for ASUS Vivobook
E1504GA and E1504GAB") does exactly what the subject says, adding DMI
matches for both the E1504GA and E1504GAB.
But DMI_MATCH() does a substring match, so checking for E1504GA will also
match E1504GAB.
Drop the unnecessary E1504GAB entry since that is covered already by
the E1504GA entry.

This reverts commit 087913e0ba2b3b9d7ccbafb2acf5dab9e35ae1d5.
It turned out that the original code was correct since the rq can only
change when there is no armed job for an entity.
This change here broke the logic since we only incremented the counter
for the first job, so revert it.

The SBDF of the target CXL 2.0 compliant root port is required to inject a CXL
protocol error as per ACPI 6.5. The SBDF given has to be in the
following format:
31 24 23 16 15 11 10 8 7 0
+-------------------------------------------------+
| segment | bus | device | function | reserved |
+-------------------------------------------------+
The SBDF calculated in cxl_dport_get_sbdf() doesn't account for
the reserved bits currently, causing the wrong SBDF to be used.
Fix said calculation to properly shift the SBDF.
Without this fix, error injection into CXL 2.0 root ports through the
CXL debugfs interface (<debugfs>/cxl) is broken. Injection
through the legacy interface (<debugfs>/apei/einj/) will still work
because the SBDF is manually provided by the user.

On a few platforms such as TI's AM69 device, disable_irq() fails to keep
track of the interrupts that happen between disable_irq() and
enable_irq() and those interrupts are missed. Use the ->irq_unmask() and
->irq_mask() methods instead of ->irq_enable() and ->irq_disable() to
correctly keep track of edges when disable_irq is called.
This solves the issue of disable_irq() not working as expected on such
platforms.

spi-cs-inactive-delay-ns in dts is cs_inactive in spi core, and it maps
to DLYCS (Minimum Inactive QCS Delay) in QSPI Mode Register (QSPI_MR).
spi-cs-hold-delay-ns in dts is cs_hold in spi core, and it maps to
DLYBCT (Delay Between Consecutive Transfers) in QSPI_MR. That one can
be set to other values than 0 only if the chip is not in Serial Memory
Mode (SMM), it must be written to '0' however when in SMM.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/spi to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
The change for the spi-npcm-fiu stands out in the diffstat because the
inconsistent formatting style of the platform_driver initializer is
fixed to match the other struct initializer in the file.

mtk_spi_slave_probe()
A clk_disable_unprepare(mdata->spi_clk) call was immediately used
after a return value check for a devm_spi_register_controller() call
in this function implementation.
Thus call such a function only once instead directly before the check.
This issue was transformed by using the Coccinelle software.
