Merge tag 'asoc-v3.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v3.17
This is mostly driver fixes, the biggest one being the tlv320aic31xx
which is relatively large but simple and device specific. There's a
small fix in the error handling in DPCM too which is relatively minor
error handling fix.
