Hi Lee,

Please check the inline comment. All other comments will be addressed

I'm going to drop off both and use risetime and falltime. That being
said, the documented risetime and falltime for lm3533 use steps instead of
entering the time directly. This is my first time doing this, should I document
risetime/falltime in sysfs-class-led-multicolor-driver-ncp5623? or should
I update risetime/falltime in sysfs-class-led-driver-lm3533 to reflect
risetime/falltime for ncp5623?
