Start from kernel 2.6.39 my TV card's PV951 radio is not work.The problem appear by partial check for option "bttv radio=1". For that

"ProVideo PV951 (42)" card.
On 2.6.38 it still fine work and form 2.6.39 to present it is not.
I have seen to source's different for BTTV code from 2.6.38 to 2.6.39
and have not seen any functional changes then the problem is generic for
Replacing card to "Pace TV & Radio Card (101)" resolve the problem for me.
I think for fix that behavior need set flag ".has_radio" or RADIO mask
for flag "bttv radio=1".
