It's helpful for reviewers when you use the -v option in git format-patch, and a change history below the --- mark also helps understand what has been modified between versions. Thanks!

Something's weird here, either you are missing a return ret;, a newline or both. This doesn't seem right.

I am also wondering if on remove you'd need to do the same thing as on suspend (disable the mic bias and cancel the workqueue)?
