Right. Don't know why I didn't do so right from the start. The thing
is, the buffer has to be seperately allocated from the heap in order
for it to be used as a dma target.
I probably overlooked that that is what actually happens in
dvb_usb_device_init. Or realized and changed everything accordingly but
forgot the .size_of_priv. ?
Anyway, that is what you get if you can't actually test what you do.
(Sorry Tino! The original patch submission had a big fat warning
that it was only compile tested, but that got lost somewhere along
the line...)
