If anyone has any objections, please let me know. ------------------ From: Vittorio Gambaletta (VittGam) commit cd84042ce9040ad038e958bc67a46fcfc015c736 upstream. The LED can be active high instead of active low on some hardware. Add the led_active_high module parameter. It defaults to -1 to obey platform data as before. Setting the parameter to 1 or 0 will force the LED respectively active high or active low.
