Merge tag 'asoc-fix-v4.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

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.
