Merge tag 'asoc-fix-v6.8-rc2-2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v6.8
This pull request adds Richard Fitzgerald's series with extensive fixes
for the CS35L56, he said:
These patches fix various things that were undocumented, unknown or
uncertain when the original driver code was written. And also a few
things that were just bugs.
