It's not OK to have a single commit that rewrites multiple drivers over
many subsystems, that's really not something that can be sensibly
reviewed.  You should split this into a patch series which makes one
specific change at a time as covered in SubmittingPatches.  That will
allow the changes to be reviewed much more sensibly.
