7678c54626 media: cedrus: Fix decoding for some HEVC videos
It seems that for some HEVC videos at least one bitstream parsing
trigger must be called in order to be decoded correctly. There is no
explanation why this helps, but it was observed that several videos
with this fix are now decoded correctly and there is no regression with
others.

Without this fix, those same videos totally crash HEVC decoder (other
decoder engines are unaffected). After decoding those problematic
videos, HEVC decoder always returns only green image (all zeros).
Only complete HW reset helps.

This fix is similar to that for H264.

spi: sh-msiof: Do not redefine STR while compile testing
STR is a well-known stringify macro so it should be avoided in drivers
to avoid warnings like this (MIPS architecture while compile testing):

    drivers/spi/spi-sh-msiof.c:76:0: warning: "STR" redefined
     #define STR 0x40 /* Status Register */
    arch/mips/include/asm/mipsregs.h:30:0: note: this is the location of the previous definition
     #define STR(x) __STR(x)

To maintain consistency between all register names add a SI prefix to
all of them.  This also matches register names in datasheet.

ASoC: max98090: fix lockdep warning
Commit 62d5ae4caf ("ASoC: max98090: save and restore SHDN when changing
sensitive registers") extended the code for handling many controls by
adding a custom put function to them. That new custom put function
properly handles relations between codec's hardware registers. However
they used card->dapm_mutex to properly serialize those operations. This
in turn triggers a lockdep warning about possible circular dependency.
Fix this by introducing a separate mutex only for serializing the SHDN
hardware register related operations.

This fixes the following lockdep warning observed on Exynos4412-based
Odroid U3 board:

feed5c7be2 drm/i915: Pin the context as we work on it
Since we now allow the intel_context_unpin() to run unserialised, we
risk our operations under the intel_context_lock_pinned() being run as
the context is unpinned (and thus invalidating our state). We can
atomically acquire the pin, testing to see if it is pinned in the
process, thus ensuring that the state remains consistent during the
course of the whole operation.

e4add24778 kprobes: Fix optimize_kprobe()/unoptimize_kprobe() cancellation logic
optimize_kprobe() and unoptimize_kprobe() cancels if a given kprobe
is on the optimizing_list or unoptimizing_list already. However, since
the following commit:

  f66c0447cc ("kprobes: Set unoptimized flag after unoptimizing code")

modified the update timing of the KPROBE_FLAG_OPTIMIZED, it doesn't
work as expected anymore.

The optimized_kprobe could be in the following states:

- [optimizing]: Before inserting jump instruction
  op.kp->flags has KPROBE_FLAG_OPTIMIZED and
  op->list is not empty.

- [optimized]: jump inserted
  op.kp->flags has KPROBE_FLAG_OPTIMIZED and
  op->list is empty.

- [unoptimizing]: Before removing jump instruction (including unused
  optprobe)
  op.kp->flags has KPROBE_FLAG_OPTIMIZED and
  op->list is not empty.

- [unoptimized]: jump removed
  op.kp->flags doesn't have KPROBE_FLAG_OPTIMIZED and
  op->list is empty.

Current code mis-expects [unoptimizing] state doesn't have
KPROBE_FLAG_OPTIMIZED, and that can cause incorrect results.

To fix this, introduce optprobe_queued_unopt() to distinguish [optimizing]
and [unoptimizing] states and fixes the logic in optimize_kprobe() and
unoptimize_kprobe().

Commit 179e5a6114 ("pinctrl: intel: Remove default Interrupt Status
offset") removes default interrupt status offset of GPIO controllers,
with previous commits explicitly providing the previously default
offsets. However, the is_offset value in SPTH_COMMUNITY is missing,
preventing related irq from being properly detected and handled.

e2b74419e5 pinctrl: baytrail: Replace WARN with dev_info_once when setting direct-irq pin to output
Suspending Goodix touchscreens requires changing the interrupt pin to
output before sending them a power-down command. Followed by wiggling
the interrupt pin to wake the device up, after which it is put back
in input mode.

On Cherry Trail device the interrupt pin is listed as a GpioInt ACPI
resource so we can do this without problems as long as we release the
IRQ before changing the pin to output mode.

On Bay Trail devices with a Goodix touchscreen direct-irq mode is used
in combination with listing the pin as a normal GpioIo resource. This
works fine, but this triggers the WARN in byt_gpio_set_direction-s output
path because direct-irq support is enabled on the pin.

This commit replaces the WARN call with a dev_info_once call, fixing a
bunch of WARN splats in dmesg on each suspend/resume cycle.

a23680594d pinctrl: baytrail: Do not clear IRQ flags on direct-irq enabled pins
Suspending Goodix touchscreens requires changing the interrupt pin to
output before sending them a power-down command. Followed by wiggling
the interrupt pin to wake the device up, after which it is put back
in input mode.

On Bay Trail devices with a Goodix touchscreen direct-irq mode is used
in combination with listing the pin as a normal GpioIo resource.

This works fine, until the goodix driver gets rmmod-ed and then insmod-ed
again. In this case byt_gpio_disable_free() calls
byt_gpio_clear_triggering() which clears the IRQ flags and after that the
(direct) IRQ no longer triggers.

This commit fixes this by adding a check for the BYT_DIRECT_IRQ_EN flag
to byt_gpio_clear_triggering().

Note that byt_gpio_clear_triggering() only gets called from
byt_gpio_disable_free() for direct-irq enabled pins, as these are excluded
from the irq_valid mask by byt_init_irq_valid_mask().

3b49b6cde5 ARM: dts: imx6ul-14x14-evk: Pass the "broken-cd" property
imx6ul-14x14-evk does not have a GPIO dedicated for reading the card
detect pin on the eSDHC2 micro-SD port.

Pass the "broken-cd" property to describe the absence of the card detect
GPIO so that polling must be used.

According to Documentation/devicetree/bindings/mmc/mmc-controller.yaml:

  broken-cd:
    $ref: /schemas/types.yaml#/definitions/flag
    description:
      There is no card detection available; polling must be used.

Even though no error is oberved in the kernel, the lack of the
'broken-cd' property caused the micro-SD to not be detected in U-Boot,
so let's improve the device tree description to make it more accurate.
