Merge tag 'asoc-3.8p1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: More updates for v3.8 Nothing terribly exciting here, just small localised changes. As well as fixes there are a couple of Cirrus changes and one devm_ change which were in prior to the merge window but got missed from the original pull to Takashi.
