NAK. This is pretty much a blunt copy of btusb.c and not acceptable.

And last time I checked, I own a big portion of btusb.c and I find it
funny how that copyright just got replaced. 2015? Really? Time travel
much lately ;)

There have been patches for hdev->setup stage and discussions on
creating a mini-driver approach on the mailing list. That is the way to
go.
