Merge tag 'asoc-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
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.
