Merge tag 'sound-6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "The amount of changes wasn't as small as wished, but all reasonably
  small fixes. There is a PCM core API change, which is for correcting
  the behavior change we took in 6.8. The rest are device-specific fixes
  for ASoC AMD, Qualcomm, Cirrus codecs, HD-audio quirks & co"
