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