This does not make any sense.  Why are you renaming a driver that has
been in the tree already?  It's not "v2", it is what we have today.

If you want to add a new driver later, great, but don't change the name
of an existing driver for no good reason.  Userspace has a tendancy to
break when that happens.

thanks,
