SubjectRegression-broken V4L2 radio API for BTTV cards (PV951)
Hello, All

Start from kernel 2.6.39 my TV card's PV951 radio is not work.
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
radio API.

For test I call command "v4l2-ctl -d /dev/radio --all -L" on 2.6.32 and
3.1.4 kernel's versions:

***************** 2.6.32 (OK) *************************
