Merge tag 'asoc-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Last minute updates These are all new code, they've been in -next already so should be OK for merge this time round. I'd been planning to send a pull request today after they'd had a bit of exposure there to make sure breakage didn't propagate into your tree.
