The Dualshock4 controller contains a RGB LED, which is enabled via the '/sys/class/leds' interface. At present the driver only returns whether each of the RGB LEDs is lit (ie not off), but no indication of it's brightness. This patch fixes the reading of the current brightnes so that it returns the value (rather than just off=0, on=LED_FULL). Tested on the DS4 and SixAxis (for compatibility).
