[PATCH] Make tda1004x DVB frontend driver work again

Adrian Bunk noticed that the tda1004x DVB frontend driver was broken and
sent a small patch that at least made the driver work again.

There was a discussion afterwards about the kernel syscall interface,
but at the end, the tda1004x DVB frontend driver is still non-functional.

This re-applies the temporary band-aid.
