Merge tag 'asoc-v3.14-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v3.14 A few things here: - Avoid memory leaks in error cases with DPCM, this code has never been that well tested in mainline due to the lack of mainline drivers but we now have one queued for the merge window! - Fix the N810 audio driver to load when booted with DT since the platform was converted to DT during the merge window. - Fixes for initialisation of some MFD drivers that are probably unused in mainline
