Merge tag 'sound-4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Very small fixes (all one-liners) at this time.

  One fix is for a PCM core stuff to correct the mmap behavior on
  non-x86. It doesn't show on most machines but mostly only for exotic
  non-interleaved formats"

* tag 'sound-4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: pcm: potential uninitialized return values
