Some bttv cards (e.g. card=24) have a tuner which can receive FM radio
but the card description doesn't have the has_radio flag set, because
the description is used for cards with and without FM capability. The
function bttv_init_tuner can detect the tuner either automatically or by
insmod option. However the original code only partly uses the detected
tuner capabilities. While the radio device node is created, the device
is not usable due to the wrong mode_mask. This patch uses the has_radio
flag from the detected tuner instead of the card description.
