Merge tag 'asoc-v3.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v3.13
A few driver and error handling fixes plus a fix to ensure that we
mute streams when we should. The Atmel trigger addition is a fix to
ensure that we do the correct sequence of interactions with the
hardware.
