this part is fine with me.

So besides the pointed of the copy-and-paste mistake, I don't think we
should be doing this. Unless you point me to hardware that actually has
a physical RFKILL button for FM. We also didn't add key define for GPS
since there is no hardware that has this.

If you think you need this for some weird handling then go one step back
and read the re-written RFKILL subsystem design.

Regards

Marcel
