5e93a125f5 ALSA: hda - Fix incorrect clearance of thinkpad_acpi hooks
Since the commit c647f806b8 ("ALSA: hda - Allow multiple ADCs for
mic mute LED controls") we allow enabling the mic mute LED with
multiple ADCs.  The commit changed the function return value to be
zero or a negative error, while this change was overlooked in the
thinkpad_acpi helper code where it still expects a positive return
value for success.  This eventually leads to a NULL dereference on a
system that has only a mic mute LED.

This patch corrects the return value check in the corresponding code
as well.

ac237c28d5 ALSA: ca0106: Disable IZD on SB0570 DAC to fix audio pops
The Creative Audigy SE (SB0570) card currently exhibits an audible pop
whenever playback is stopped or resumed, or during silent periods of an
audio stream. Initialise the IZD bit to the 0 to eliminate these pops.

The Infinite Zero Detection (IZD) feature on the DAC causes the output
to be shunted to Vcap after 2048 samples of silence. This discharges the
AC coupling capacitor through the output and causes the aforementioned
pop/click noise.

The behaviour of the IZD bit is described on page 15 of the WM8768GEDS
datasheet: "With IZD=1, applying MUTE for 1024 consecutive input samples
will cause all outputs to be connected directly to VCAP. This also
happens if 2048 consecutive zero input samples are applied to all 6
channels, and IZD=0. It will be removed as soon as any channel receives
a non-zero input". I believe the second sentence might be referring to
IZD=1 instead of IZD=0 given the observed behaviour of the card.

This change should make the DAC initialisation consistent with
Creative's Windows driver, as this popping persists when initialising
the card in Linux and soft rebooting into Windows, but is not present on
a cold boot to Windows.

5e3cdecf78 ASoC: Updates for v5.0/v4.20
As ever there's a lot of small and driver specific changes going on
 here, but we do also have some relatively large changes in the core
 thanks to the hard work of Charles and Morimoto-san:
 
  - More component transitions from Morimoto-san, I think we're about
    finished with this.  Thanks for all the hard work!
  - Morimoto-san also added a bunch of for_each_foo macros
  - A bunch of cleanups and fixes for DAPM from Charles.
  - MCLK support for several different devices, including CS42L51, STM32
    SAI, and MAX98373.
  - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
    MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
    TI PCM3060.

bf85a91c2f ALSA: hda/ca0132 - Define new verbs and control params
This patch defines some new verbs found from reverse engineering of the
onboard 8051 CPU, and a control param found there as well. This clears
up usage of these verbs in other parts of the driver, and removes their
usage where they're now known to be unnecessary.

37a3a98ef6 ALSA: hda - Enable runtime PM only for discrete GPU
The recent change of vga_switcheroo allowed the runtime PM for
HD-audio on AMD GPUs, but this also resulted in a regression.  When
the HD-audio controller driver gets runtime-suspended, HD-audio link
is turned off, and the hotplug notification is ignored.  This leads to
the inconsistent audio state (the connection isn't notified and ELD is
ignored).

The best fix would be to implement the proper ELD notification via the
audio component, but it's still not ready.  As a quick workaround,
this patch adds the check of runtime_idle and allows the runtime
suspend only when the vga_switcheroo is bound with discrete GPU.
That is, a system with a single GPU and APU would be again without
runtime PM to keep the HD-audio link for the hotplug notification and
ELD read out.

Also, the codec->auto_runtime_pm flag is set only for the discrete GPU
at the time GPU gets bound via vga_switcheroo (i.e. only dGPU is
forcibly runtime-PM enabled), so that APU can still get the ELD
notification.

For identifying which GPU is bound, a new vga_switcheroo client
callback, gpu_bound, is implemented.  The vga_switcheroo simply calls
this when GPU is bound, and tells whether it's dGPU or APU.

7064f376d4 ALSA: intel8x0m: Register irq handler after register initializations
The interrupt handler has to be acquired after the other resource
initialization when allocated with IRQF_SHARED.  Otherwise it's
triggered before the resource gets ready, and may lead to unpleasant
behavior.
