Merge tag 'sound-5.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "A collection of small fixes.

  The major changes are ASoC core fixes, addressing the DPCM locking
  issue after the recent code changes and the potentially invalid
  register accesses via control API. Also, HD-audio got a core fix for
  Oops at dynamic unbinding.

  The rest are device-specific small fixes, including the usual stuff
  like HD-audio and USB-audio quirks"
