That would work.

Better patch splitting would be 

1. Remove the polarity switching of the clock for the DVB-C cards in
   budget-av.c. This hack is no longer necessary because the saa7146 can
   do the job to remove the additional FEC bytes from the TS.stays

2. Add support for the frontend TDA10023 and add cards that need the
   tda10023.

3. Make the inversion setting configurable. The KNC ONE V1.0 uses
   non inverted setting for the inversion and add the KNC ONE V1.0 card.

thanks

Janne
