A bug in cx8802_get_driver() meant that in multiboard environments, when testing
frontends on the non primary board, the incorrect device was returned resulting
in "Unsupported value in .mpeg.." messages. Depending on the electrical design
of the hardware (serial, parallel, rising/falling edge detect), transport would
still be delivered and the problem went unnoticed.
This patch ensures the correct instance of cx8802_dev is returned.
