Merge tag 'sound-5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "The important fixes at this time are a couple fixes in ALSA core: a
  fix for PCM is about the OOB access in PCM OSS plugins that has been
  for long time, but hasn't hit so often until now just because we
  allocated a large buffer via vmalloc(), and surfaced more often after
  switching to kvmalloc(). Another fix is for a long-standing PCM
  problem wrt racy PM resume.

  Others are trivial nospec coverage and usual HD-audio quirks"
