Pavel,

Either your clock is really off or it took you 3 weeks to get this
message out ;)  Just letting you know.

I am not entirely clear what you are referring to.  If it is the double
colon, that seems to be the convention used throughout the
platform-driver-x86 tree.  If it is the LED's name ("radio_led"), I
failed to find a similarly purposed LED in the platform-driver-x86 tree
with a name I could reuse.  I decided to use the _led suffix to
differentiate this LED from the "lamps" already implemented by
fujitsu-laptop.

I have covered this issue in the lengthy comment attached to this patch:

I haven't found a way to make this work the intended way out of the box,
not with the currently available set of LED triggers.  That being said,
I would be happy if someone proved me wrong.
