Merge tag 'sound-fix-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
 "Here is a collection of small fixes on top of the previous update.

  All small and obvious fixes. Mostly for usual suspects, USB-audio and
  HD-audio, but a few trivial error handling fixes for misc drivers as
  well"
