It would've been easier for me if you had just posted a patch for the specfile
along with the patch you wanted to apply to the source.

Anyway, I had a look at it and I don't like it. You're hardcoding the driver
to v4l2. I think it'd be better to simply make the autodetection try v4l2
first. Also, is it necessary to change "/dev/radio" to "/dev/radio0"?


There is no /dev/radio in Fedora 12 any more. Only /dev/radio0.
But this is up to you, because it can be set using the interface.

 
Please try the attached patch and see if it works for you.


It worked just fine, and it is much better indeed. This way, the default
can be "any", and it will work with v4l2.

It is also working in Fedora 10 for me.


Thanks.
