NACK

If this is only for K54C (works fine on my G73 anyway) then you must
do some kind of DMI matching right ? Or at least check that this led
is present. Do you have any list of laptops that export this LED and
how it behave ?

Anyway, you should use a led trigger for that, ideally the rfkill%d
led trigger, but for that you need the rfkill idx, which is not
exported, so you may need a new rfkill_idx() function. CCing rfkill
and led guys, they may have a better advice on that.
