Wow, finally we have support for this card!
I just had a glance at your patch. Looks good, but i have a question:
Is it really necessary to duplicate the tuning code? It would be good if
you could avoid this.
A Note: When i have time left, i wish to rework the saa7134-dvb module. I hope
that i can move the tunig code to dvb-pll.c to have a central place.
Best regards
