Merge tag 'asoc-fix-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linussound-4.3-rc7
ASoC: Fixes for v4.3
A bunch of driver fixes plus one core fix which fixes problems with
misreporting values from _SX controls following a recent refactoring.
This had gone unnoticed as such controls are quite rare.
