Merge tag 'sound-fix-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "A collection of fixes for 5.16-rc1, notably for a few regressions that
  were found in 5.15 and pre-rc1:

   - revert of the unification of SG-buffer helper functions on x86 and
     the relevant fix

   - regression fixes for mmap after the recent code refactoring

   - two NULL dereference fixes in HD-audio controller driver

   - UAF fixes in ALSA timer core

   - a few usual HD-audio and FireWire quirks"
