Yeah, what Lars said - obviously the patch removing the driver is more
comprehensive!

For the record it's very helpful to be specific about what the problem

that's being fixed is that'll slow things down.  Please also use subject
lines appropriate for the subsystem, it will help your patch get
noticed.
