But not merged. I think this is a bit too quick. It is good practice to wait
with making such changes to v4l-utils until Mauro has merged the videodev2.h
changes as well.

You can always make a clone of v4l-utils and keep your changes there until it
can be merged in the main v4l-utils repository.

I also have a small request:

+static const char *band_names[] = {
+       "default",
+       "fm-eur_us",
+       "fm-japan",
+       "fm-russian",
+       "fm-weather",
+       "am-mw",
+};

Can you rename "fm-eur_us" to "fm-eur-us"? That mix of '-' and '_' is very
jarring and awkward to type IMHO.

Regards,

	Hans

Ok, next time around I'll wait.
