Merge tag 'asoc-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.12 A quiet release for the core, but lots of new drivers this time around: - A new, generalized, API for hooking up jacks which makes it easier to write generic machine drivers for simple cases. - Continuing fixes for issues with the x86 CPU drivers. - New drivers for Cirrus CS35L35, DIO DIO2125, Everest ES7132, HiSilicon hi6210, Maxim MAX98927, MT2701 systems with WM8960, Nuvoton NAU8824, Odroid systems, ST STM32 SAI controllers and x86 systems with DA7213
