Pull sound updates from Takashi Iwai:
"Nothing too thrilling here, but we see lots of driver updates and bug
fixes, including quirk additions and refactoring works, while there
have been little changes in the core functionality. Here are some
highlights:

Core:
- Add validation for the control API put callback
- Fixes in compress-offload API timestamp handling
- Continued ASoC core API cleanups

ASoC:
- Add support for bus keepers (for Apple devices in future)
- Enhancements to the SDCA support, including retaskable jacks
- Test improvements for Cirrus Logic drivers
- Lots of fixes for the NXP, nVidia and Qualcomm
- Support for AMD RPL DMIC, Cirrus Logic CS42L43 and CS47L47, nVidia
machines with CPCAP and WM8962

USB-audio:
- Quirks for Huawei Headset, Focusrite Novation, MV-Silicon, Studio
1824, Arturia AF16Rig, Hotone Audio, Feaulle Rainbow, PreSonus
AudioBox, Moondrop Ju Jiu, Scarlett 18i20, etc
- Extended mixer volume quirk handling
- UAF and other fixes for us144mkii, 6fire and caiaq drivers

HD-audio:
- Add quirks or fixes for Acer, Lenovo, HP, ASUS machines
- Fixes & cleanups of GPIO helper code

Misc:
- Add suspend/resume support for multiple legacy ISA and Apple
drivers
- Further regression fixes for ctxfi driver"

ALSA: control: Verify put() result when in debug mode

The put() operation is expected to return:
1) 0 on success if no changes were made
2) 1 on success if changes were made
3) error code otherwise

ALSA: control: Verify put() result when in debug mode

The put() operation is expected to return:
1) 0 on success if no changes were made
2) 1 on success if changes were made
3) error code otherwise

Currently 2) is usually ignored when writing control-operations. While
forcing compliance is not an option right now, make it easier for
developers to adhere to the expectations and notice problems by logging
them when CONFIG_SND_CTL_DEBUG is enabled.

Due to large size of struct snd_ctl_elem_value, 'value_buf' is provided
as a reusable buffer for kctl->put() verification. This prevents
exhausting the stack when verifying the operation.

>From user perspective, patch introduces a new trace/events category
'snd_ctl' containing a single 'snd_ctl_put' event type. Log sample:

amixer-1086 [003] ..... 8.035939: snd_ctl_put: success: expected=0, actual=0 for ctl numid=1, iface=MIXER, name='Master Playback Volume', index=0, device=0, subdevice=0, card=0
amixer-1087 [003] ..... 8.938721: snd_ctl_put: success: expected=1, actual=1 for ctl numid=1, iface=MIXER, name='Master Playback Volume', index=0, device=0, subdevice=0, card=0

amixer-1089 [000] ..... 9.636786: snd_ctl_put: fail: expected=1, actual=0 for ctl numid=5, iface=MIXER, name='Loopback Mute', index=0, device=0, subdevice=0, card=0
