cbf7dcd949 ALSA: emu10k1: Use managed buffer allocation
Clean up the driver with the new managed buffer allocation API.
The normal playback streams need a workaround for the aligned buffer,
and cannot apply the straight snd_pcm_lib_malloc() stuff, so they
remain untouched, while other streams are converted to the new managed
mode.

Most of hw_params and hw_free callbacks became superfluous and got
dropped.

88452da92b ALSA: hda: Use standard waitqueue for RIRB wakeup
The HD-audio CORB/RIRB communication was programmed in a way that was
documented in the reference in decades ago, which is essentially a
polling in the waiter side.  It's working fine but costs CPU cycles on
some platforms that support only slow communications.  Also, for some
platforms that had unreliable communications, we put longer wait time
(2 ms), which accumulate quite long time if you execute many verbs in
a shot (e.g. at the initialization or resume phase).

This patch attempts to improve the situation by introducing the
standard waitqueue in the RIRB waiter side instead of polling.  The
test results on my machine show significant improvements.  The time
spent for "cat /proc/asound/card*/codec#*" were changed like:

* Intel SKL + Realtek codec
  before the patch:
   0.00user 0.04system 0:00.10elapsed 40.0%CPU
  after the patch:
   0.00user 0.01system 0:00.10elapsed 10.0%CPU

* Nvidia GP107GL + Nvidia HDMI codec
  before the patch:
   0.00user 0.00system 0:02.76elapsed 0.0%CPU
  after the patch:
   0.00user 0.00system 0:00.01elapsed 17.0%CPU

So, for Intel chips, the total time is same, while the total time is
greatly reduced (from 2.76 to 0.01s) for Nvidia chips.
The only negative data here is the increase of CPU time for Nvidia,
but this is the unavoidable cost for faster wakeups, supposedly.

6e8aeda224 ALSA: hda/hdmi - Fix duplicate unref of pci_dev
Nicholas Johnson reports a null pointer deref as well as a refcount
underflow upon hot-removal of a Thunderbolt-attached AMD eGPU.
He's bisected the issue down to commit 586bc4aab8 ("ALSA: hda/hdmi -
fix vgaswitcheroo detection for AMD").

The commit iterates over PCI devices using pci_get_class() and
unreferences each device found, even though pci_get_class()
subsequently unreferences the device as well.  Fix it.

ASoC: Intel: common: work-around incorrect ACPI HID for CML boards
On CML boards with the RT5682 headset codec and RT1011 speaker
amplifier, the platform firmware exposes three ACPI HIDs
(10EC5682, 10EC1011 and MX98357A). The last HID is a mistake in
DSDT tables, which causes the wrong machine driver to be loaded.

This patch changes the key used to identify boards and changes the
order of entries in the table to load the correct machine driver.
The order does matter and should not be modified to work-around this
firmware issue.

ASoC: SOF: Intel: split cht and byt debug window sizes
Turns out SSP 3-5 are only available on cht, to avoid dumping on
undefined registers let's split the definition.

ASoC: SOF: loader: fix snd_sof_fw_parse_ext_data
An error occurs during parsing more than one ext_data from the mailbox, because
of invalid data offset handling. Fix by removing the incorrect duplicate
increment of the offset.

The return value is also reset in the switch case. This does not change the
behavior but improves readability - there is no longer a need to check what the
return value of get_ext_windows is.

ASoC: simple-card: Don't create separate link when platform is present
In normal sound case all DAIs are detected as CPU-Codec.
simple_dai_link_of supports the presence of a platform but it counts
it as a CPU DAI resulting in the creation of an extra link.

Adding a platform property to a link description like:

simple-audio-card,dai-link {
	cpu {
		sound-dai = <&sai1>;
	};
	plat {
		sound-dai = <&dsp>;
	};
	codec {
		sound-dai = <&wm8960>;
	}

will result in the creation of two links:
	* sai1 <-> wm8960
	* dsp  <-> wm8960

which is obviously not what we want. We just want one single link
with:
	* sai1 <-> wm8960 (and platform set to dsp).
