That patch was pure garbage, I think. Pretty much all the other
drivers that use the same approach will have the same issue. Adding
that init function just for the semaphore is crazy.
I suspect a much simpler approach is to just miove the "data_mutex"
away from the priv area and into "struct dvb_usb_device" and
"dvb_usb_adapter". Sure, that grows those structures a tiny bit, and
not every driver may need that mutex, but it simplifies things
enormously. Mauro?
