Hello All!
And thank for comments Hans and Mauro.
Here is the list of changes from v5:

Changed the name to v4l2_fm_band. Also changed the define constant.

Added code...

Yes, good idea, I'll send it to the ALSA list...

I don't think you are missing anything. I've added code for RX and TX.

Fixed. There was also another strcpy. Fixed also that.

Stereo and mono modes can be detected. ALSA can also handle both...
The codec conforms automatically to the audio source/sink.

Added.

Filled...

Actually there is...

I agree.

Handling added.

I agree... I kind of left the stereo/mono stuff to alsa...

OK. I put kHz as the spacing unit, that should be fine grained enough? I also
reformulated the text somewhat. And yes, I didn't notice Mauro's comments on
v4 patch set. But now I've read his comments and also given some comments
back.
