Merge tag 'asoc-fix-v4.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linussound-4.8-rc4
ASoC: Fixes for v4.8 A clutch of fixes for v4.8. These are mainly driver specific, the most notable ones being those for OMAP which fix a series of issues that broke boot on some platforms there when deferred probe kicked in. There's also one core fix for an issue when unbinding a card which for some reason had managed to not manifest until recently.
