Same issue with clarifying the authorship. Also for these fixes
ideally include a 'fixes' tag to the original commit. It makes
life easy for the scripts the stable maintainers use to work
out when things should apply.

Here I would imagine it is the original commit that added the driver,
though we may have had enough changes over the years to make these
hard to apply.
