My rtl8187 devices are both external USB sticks, thus they have no interaction 
with a radio-kill switch. I will test your patch to make sure it does no harm to 
my system.

I think the commit message should be revised. A simple statement like "the LED 
does not turn off when the rfkill switch is off" should be sufficient.
