Merge tag 'sound-4.13-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai...

Pull sound fixes from Takashi Iwai:
 "Three regression fixes that should be addressed before the final
  release: a missing mutex call in OSS PCM emulation ioctl, ASoC rt5670
  headset detection breakage, and a regression in simple-card parser
  code"

* tag 'sound-4.13-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ASoC: simple_card_utils: fix fallback when "label" property isn't present
  ALSA: pcm: Fix power lock unbalance via OSS emulation
  ASoC: rt5670: Fix GPIO headset detection regression
