Merge tag 'sound-4.17-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 

Pull sound fixes from Takashi Iwai:
 "We have a core fix in the compat code for covering a potential race
  (double references), but it's a very minor change.

  The rest are all small device-specific quirks, as well as a correction
  of the new UAC3 support code"
