Merge tag 'asoc-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.14 This is quite a large release by volume of patches and diff, a lot of that is mechanical cleanup patches but it's great to also see a range of vendors actively working on adding new features and fixing issues in their drivers. Intel and Realtek have been especially active here. - Continued work towards moving everything to the component model from Morimoto-san. - Use of devres for jack detection GPIOs, eliminating some potential resource leaks. - Jack detection support for Qualcomm MSM8916. - Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson WM8523.
