Linus,

please pull sound fixes for v3.18-rc1 from:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/sound-fix-3.18-rc1

The topmost commit is c8b00fd2f4c504a564adcad5b8bd6952ab850b02

sound fixes for 3.18-rc1

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.

----------------------------------------------------------------

James Ralston (1):
ALSA: hda_intel: Add Device IDs for Intel Sunrise Point PCH

Takashi Iwai (2):
ALSA: pcm: Fix referred substream in snd_pcm_action_group() unlock loop
ALSA: emu10k1: Fix deadlock in synth voice lookup

Takashi Sakamoto (1):
ALSA: bebob: Fix failure to detect source of clock for Terratec Phase 88
