Merge tag 'sound-fix-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 

Pull sound fixes from Takashi Iwai:
 "Here are a collection of small fixes after 3.18 merge.

  The urgent one is the fix for kernel panics with linked PCM substream
  triggered by the recent nonatomic PCM ops support.  Other two fixes
  (emu10k1 and bebob) are stable fixes, and one easy PCI ID addition for
  a new Intel HD-audio controller"

  ALSA: hda_intel: Add Device IDs for Intel Sunrise Point PCH
  ALSA: emu10k1: Fix deadlock in synth voice lookup
  ALSA: pcm: Fix referred substream in snd_pcm_action_group() unlock loop
  ALSA: bebob: Fix failure to detect source of clock for Terratec Phase 88
