Obtaining the runtime pm wakeref can fail, especially in a hotplug
scenario where i915.ko has been unloaded. If we do not catch the
failure, we end up with an unbalanced pm.

v2 additions by tiwai:
hdmi_present_sense() checks the return value and handle only a
negative error case and bails out only if it's really still suspended.
Also, snd_hda_power_down() is called at the error path so that the
refcount is balanced.

Along with it, the spec->pcm_lock is taken outside
hdmi_present_sense() in the caller side, so that it won't cause
deadlock at reentrace via runtime resume.

v3 fix by tiwai:
Missing linux/pm_runtime.h is included.

We have 3 more Lenovo machines, they all have 2 front mics on them,
so they need the fixup to change the location for one of two mics.

Among these 3 Lenovo machines, one of them has the same pin cfg as the
machine with subid 0x17aa3138, so use the pin cfg table to apply fixup
for them. The rest machines don't share the same pin cfg, so far use
the subid to apply fixup for them.

Henning Kühn reported that the discrete AMD GPU on his hybrid graphics
laptop no longer runtime-suspends due to the recent commit
07f4f97d ("vga_switcheroo: Use device link for HDA controller").

The root cause is that the HDMI codec on AMD GPU doesn't support
CLKSTOP and EPSS, which are currently mandatory for powering down the
HD-audio link at runtime suspend.  Because the HD-audio link is still
up, HD-audio controller driver blocks the transition to D3.

For addressing the regression, this patch adds a new flag to indicate
the forced link-down, and sets it for AMD HDMI codecs appropriately
in the codec driver.

The commentary says to use various parameters, and lays out what
the mapping is...  The code used a 32KHz rate when the comment
says that it needs to use a 48KHz rate.  And this has been the
case since day one.

On the Alienware M17x R4, the DMic used to have exceptionally quiet
pickup and a lot of noise.  Changing the data rate fixes both of
these issues.

Searching the kernel bug tracker for ca0132-related issues shows no
mention of this being an issue for other hardware, and I have no
other hardware to test with, so a quirk is used to limit the effect
to just the M17x R4.

QUIRK_NONE is, quite explicitly, the default case.  The entire
point of a quirks system is to allow "programming by difference"
from a given base case, which requires that merely defining a new
quirk for some piece of hardware should not change the behavior of
the driver for that hardware.  In turn, this means that testing
for QUIRK_NONE explicitly is a violation of that implicit contract.

Change a test for QUIRK_NONE and QUIRK_ALIENWARE to default, and
add a test for QUIRK_SBZ to disable the default behavior in that
instance.

Some Lenovo laptops, e.g. Lenovo P50, showed the pop noise at resume
or runtime resume.  It turned out to be reduced by applying
alc_no_shutup() just like TPT440 quirk does.

Since there are many Lenovo models showing the same behavior, put this
workaround in ALC269_FIXUP_THINKPAD_ACPI entry so that it's applied
commonly to all such Lenovo machines.

As files got renamed, their references broke.

Manually fix a series of broken refs at the DT bindings.

Rename:
	pinctrl-binding.txt -> pinctrl-bindings.txt

In order to match the current name of this file.

There were some file movements that changed the location for
some DT bindings. Fix them with:
	scripts/documentation-file-ref-check --fix

After manually checking if the new file makes sense.

The specified locations are not right. Fix the wildcard logic
to point to the correct directories.

Without that, get-maintainer won't get things right:

	$ ./scripts/get_maintainer.pl --no-git-fallback --no-r --no-n --no-l -f Documentation/devicetree/bindings/arm/cpu-enable-method/nuvoton,npcm750-smp
	robh+dt@kernel.org (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
	mark.rutland@arm.com (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)

After the patch, it will properly point to NPCM arch maintainers:
	$ ./scripts/get_maintainer.pl --no-git-fallback --no-r --no-n --no-l -f Documentation/devicetree/bindings/arm/cpu-enable-method/nuvoton,npcm750-smp
	avifishman70@gmail.com (supporter:ARM/NUVOTON NPCM ARCHITECTURE)
	tmaimon77@gmail.com (supporter:ARM/NUVOTON NPCM ARCHITECTURE)
	robh+dt@kernel.org (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
	mark.rutland@arm.com (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)

Those files got a manufacturer's name prepended and were moved around.
Adjust their references accordingly.

Also, due those movements, Documentation/devicetree/bindings/video
doesn't exist anymore.

The alsa parameters file was renamed to alsa-configuration.rst.

With regards to OSS, it got retired as a hole by  at changeset
727dede0 ("sound: Retire OSS"). So, it doesn't make sense
to keep mentioning it at kernel-parameters.txt.

Fixes: 727dede0 ("sound: Retire OSS")

As we move stuff around, some doc references are broken. Fix some of
them via this script:
	./scripts/documentation-file-ref-check --fix
