ok. I see the problem now. The buffer get's initialzed a little bit too late
because it already get's used from the dvb_usb_device_init call via the
frontend attach call:
dvb_usb_device_init->dvb_usb_init->dvb_usb_adapter_init->dvb_usb_adapter_frontend_init->vp7045_frontend_attach->vp7045_usb_op
Hm.. let me think about it. In the meantime, you don't need to test
this 'fix'.
Regards,
Flo
