Merge tag 'asoc-fix-v4.8-rc4' into asoc-arizona
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.
