1) What do you think about adding a void *priv_tuner to dvb_frontend?

And a tuner would use that, instead of passing a void* in the argument of 
the function pointer?

2) Why not creating a struct dvb_tuner and struct dvb_tuner_ops? and a 
dvb_frontend would then also contain an optional pointer to a 
dvb_tuner-struct?

With that idea we could even move the dvb_frontend_ops to a dvb_demod and 
a dvb_demod_ops-struct and a dvb_frontend would consist of dvb_demod 
+ dvb_tuner.

Just my thoughts - maybe too radical. But what about the first one?

best regards,
Patrick.
