The better is to ask such questions on linux-media@...r.kernel.org. Anyway, the
issue is likely due to a wrong entry at cx88-cards for your board. In order to
fix, someone with your board (probably you)should get the proper GPIO pins for
your device. Please read the following wiki articles:

Cheers,
Mauro
