I can split the patch into four steps:

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.
2.) Add support for the frontend TDA10023.
3.) Make the inversion setting configurable. The KNC ONE V1.0 uses non
inverted setting for the inversion.
4.) Add the the new cards (Satelco Easywatch DVB-C with id 1894:002c,
KNC ONE DVB-C with id 1894:0022, KNC ONE PLUS DVB-C with id 1894:0023,
Terratec Cinergy 1200 DVB-C with id 153b:1176, KNC ONE DVB-C V1.0)

 I'm not sure if this make sense. One card needs step 1 and 3. All other
cards need step 1 and 2.
