Merge tag 'asoc-fix-v7.2-rc1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Fixes for v7.2 A fairly standard set of driver specific fixes and quirks that have come in since the merge window, plus a MAINTAINERS update. The tas675x READ_ONCE change is probably not actually fixing issues properly but we need a whole new approach to concurrency there and it came along with some good fixes.
