Pull sound fixes from Takashi Iwai:
 "Small last-minute fixes for 4.13-rc1: a couple of PCM fixes for m68k,
  a cleanup work for legacy ISA msnd driver, and a few HD-audio new IDs
  and quirks"

* tag 'sound-fix-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
  ALSA: hda - Add hdmi id for a Geminilake variant
  ALSA: hda/realtek - New codec device ID for ALC1220
  ALSA: pcm: Simplify check for dma_mmap_coherent() availability
  ALSA: pcm: Protect call to dma_mmap_coherent() by check for HAS_DMA
  ALSA: msnd: Optimize / harden DSP and MIDI loops
  ALSA: hda/realtek - change the location for one of two front microphones
  ALSA: opl4: Move inline before return type
