The SOB doesn't match with From line.  Is it intentional?
I missed this sorry. Have corrected.

Please drop the unrelated change.
Looks like my vim settings removed an ending white-space. I'll remove the change.

Remove braces for a single if line.  Checkpatch would suggest it, too.
Done

The doubly comments look awkward.  Please reformat it.
Missed this also, sorry :(

Use AC_VERB_SET_DIGI_CONVERT_1.
And, how is this related with the headset fix?  Is this really
mandatory?  If this widget is really wired, usually the digital I/O is
controlled via IEC9158 status mixer.
This I'm not actually sure about, I'm sort of fumbling around trying to get the rear mic jack working. I have now removed the comment and 0x0a line so the patch is
focused solely on the headset.

Many thanks for the code review. I will submit the fixed version now.

Kind regards,
Luke.
