Subject[GIT PULL] sound fixes for 3.16-rc7
Linus,

please pull sound fixes for v3.16-rc7 from:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/sound-3.16-rc7

The topmost commit is eb12f72ee7245ca207818b9efd10be2641494502

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

sound fixes for 3.16-rc7

Here contains only the fixes for the new FireWire bebob driver.
All fairly trivial and local fixes, so safe to apply.

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

Takashi Sakamoto (4):
ALSA: bebob: Fix a missing to unlock mutex in error handling case
ALSA: bebob: Use different labels for digital input/output
ALSA: bebob: Correction for return value of .put callback
ALSA: bebob: Correction for return value of special_clk_ctl_put() in error
