[PATCH v3 0/6] ALSA: some driver fixes for control input validations

[Takashi Iwai <tiwai@suse.de>]

Hi,

this is a v3 patch set as a follow up of the thread about the errors
reported by kselftest mixer-test.  It changes HD-audio and vmaster
control behavior to return -EINVAL for invalid input values.

There is a change in kselftest itself to skip the verification after
write tests for volatile controls, too.  It's for the channel map
controls that can't hold the stable values.

v2->v3:
* Replace with Mark's patch for kselftest
* Apply the validation for user controls in put callback instead

v1->v2:
* Skip only verification after write in kselftest
* Add sanity check to HDMI chmap write, too

v2: https://lore.kernel.org/r/20240614153717.30143-1-tiwai@suse.de
v1: https://lore.kernel.org/r/20240614124728.27901-1-tiwai@suse.de
