A similar patch got applied already, sent by Johannes:

commit b43ea8068d2090cb1e44632c8a938ab40d2c7419
Author: Johannes Koch <johannes@xxxxxxxxxxx>
Date:   Wed Jul 17 14:28:16 2013 -0300

    [media] cx23885: Fix TeVii S471 regression since introduction of ts2020
    
    Patch to make TeVii S471 cards use the ts2020 tuner, since ds3000 driver no
    longer contains tuning code.

The difference between your patch and the applied one is:

So, basically, on our patch, you're also filling ops.set_voltage. 

As I don't know the board details, I can't tell if this is required or
not.

Christian/Johannes,

Could you please double-check it? If this is needed, please send me a new
patch, rebased on the top of linux-media git tree.

Thanks!
Mauro
