switch (bw) {
case BANDWIDTH_8_MHZ:
if (p->frequency < 470000000)
priv->ctrl.vhfbw7 = 0;
else
priv->ctrl.uhfbw8 = 1;
type |= (priv->ctrl.vhfbw7 && priv->ctrl.uhfbw8) ? DTV78 : DTV8;
type |= F8MHZ;
break;
case BANDWIDTH_7_MHZ:
if (p->frequency < 470000000)
priv->ctrl.vhfbw7 = 1;
else
priv->ctrl.uhfbw8 = 0;
type |= (priv->ctrl.vhfbw7 && priv->ctrl.uhfbw8) ? DTV78 : DTV7;
type |= F8MHZ;
break;
case BANDWIDTH_6_MHZ:
type |= DTV6;
priv->ctrl.vhfbw7 = 0;
priv->ctrl.uhfbw8 = 0;
break;
default:
tuner_err("error: bandwidth not supported.\n");
};
That is the actually part from tuner-xc2028.c, but I think here is the
checking wrong if Bandwidth 8 MHz & frequency < 470 MHz then DTV8, and
if Bandwidth 7 MHz & frequency => 470 MHz then DTV7. The first check in
code is OK, but the second check in code is not OK.
