Merge tag 'asoc-v3.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v3.14 A few fixes, all driver speccific ones. The DaVinci ones aren't as clear as they should be from the subject lines on the commits but they fix issues which will prevent correct operation in some use cases and only affect that particular driver so are reasonably safe.
