One small point. Don't put the word bugfix in the title (and fix
spelling of enable!).  I know this is obviously a false restriction
on the driver, but it doesn't not work, it is just limited in features

This issue is that this is not really material that should be going
into stable kernels.  It's an improvement though so good to have it!
