Merge tag 'asoc-v3.15-5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v3.15 A smattering of device specific fixes, nothing stands out here except for the multiplatform fixes for Samsung and the device IDs being added by Stephen Warren - there's no real code changes from those and they give better robustness to the enumeration with DT.
