Merge tag 'asoc-v5.1-2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: More changes for v5.1 Another batch of changes for ASoC, no big core changes - it's mainly small fixes and improvements for individual drivers. - A big refresh and cleanup of the Samsung drivers, fixing a number of issues which allow the driver to be used with a wider range of userspaces. - Fixes for the Intel drivers to make them more standard so less likely to get bitten by core issues. - New driver for Cirrus Logic CS35L26.
