<div class='commit-subject'>Merge tag 'asoc-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next</div><div class='commit-msg'>ASoC: Updates for v4.9

Apart from the cleanups done by Morimoto-san this has very much been a
driver focused release with very little generic change:

 - A big factoring out of the simple-card code to allow it to be shared
   more with the rcar generic card from Kuninori Morimoto.
 - Removal of some operations duplicated on the CODEC level, again by
   Kuninori Morimoto.
 - Lots more machine support for x86 systems.
 - New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663.
