Merge tag 'asoc-v4.2-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.3 Not many updates to the core here, but an awful lot of driver updates this time round: - Factoring out of AC'97 reset code into the core - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers. - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650. - Initial driver support for Intel Skylake devices. - A large number of cleanups for Lars-Peter Clausen and Axel Lin.
