In case of an e.g. gpio led this is true. But in case of pwm driven leds, where someone could dimm the leds, the value of 1 dimms the led. Use the max value for blinking and flashing of a led when enabling.

2017-03-30	7dd8ae8 Browse files » led-trigger: Allow multiple led triggers of the same type ... We used to have a static array of trigger types which, allows only one led per trigger. While this is enough for panic and heartbeat, it falls short when multiple leds are associated to the default-on trigger. The default-on trigger is used to turn on a led statically from devicetree and may be used multiple times. This patch reworks the led triggers so that a trigger struct is allocated dynamically when needed and put onto a list.
