Merge tag 'asoc-fix-v3.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v3.19 A few last minute fixes for v3.19, all driver specific. None of them stand out particularly - it's all the standard people who are affected will care stuff. The Samsung fix is a DT only fix for the audio controller, it's being merged via the ASoC tree due to process messups (the submitter sent it at the end of a tangentally related series rather than separately to the ARM folks) in order to make sure that it gets to people sooner.
