em28xx: VideoMate For You USB TV box requires tvaudio
From: Mauro Carvalho Chehab <mchehab@redhat.com>
As reported by Vitaly Wool <vital@embeddedalley.com>:
> about half a year ago I posted the patch that basically enabled Compro
> VideoMate For You USB TV box support.
> The main problem is I couldn't get the sound working.
> So I kind of decomposed the box and found out the audio decoder chip

> within the em28xx suite although it is for other TV tuner drivers.
A tvaudio modprobing confirms that tda9874a chip is accessible via i2c:
tvaudio: TV audio decoder + audio/video mux driver
tvaudio: known chips: tda9840, tda9873h, tda9874h/a, tda9850, tda9855, tea6300, tea6320, tea6420, tda8425, pic16c54 (PV951), ta8874z
