Merge tag 'asoc-fix-v4.6-rc5' into asoc-intel
ASoC: Fixes for v4.6 This is a fairly large collection of fixes but almost all driver specific ones, especially to the new Intel drivers which have had a lot of recent development. The one core fix is a change to the debugfs code to avoid crashes in some relatively unusual configurations.
