ASoC: Fixes for v6.8

Browse Source 
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.
