Merge tag 'asoc-fix-v4.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v4.4
Quite a large batch of fixes have come in since the merge window, mainly
driver specific ones but there's a couple of core ones:
- A fix for DAPM resume on active streams to ensure everything ends up
cleanly in the right state.
- Reset the DAPM cache when freeing widgets to fix a crash on driver
remove and reload.
The PM functions for nau8825 are new code which fix crashes on resume.
