The cause is in bttv-driver.c :
static int radio_open(struct video_device *dev, int flags)
{
struct bttv *btv = (struct bttv *)(dev-1);
unsigned long v;
down(&btv->lock);
if (btv->user)
goto busy_unlock;
btv->user++;
btv->radio = 1;
v = 400*16; // <--- here
bttv_call_i2c_clients(btv,VIDIOCSFREQ,&v); // <--- and here
bttv_call_i2c_clients(btv,AUDC_SET_RADIO,&btv->tuner_type);
bt848_muxsel(btv,0);
up(&btv->lock);
return 0;
busy_unlock:
up(&btv->lock);
return -EBUSY;
}
Why are those two lines there ?
They try to set the tuner to 400 MHz, but that is illegal for radio
and is flaged as such deeper in the code.
Does anybody maintain this driver ?
