Just to let you know - I am currently playing with Samsung Galaxy S3,
which has mainline support, and also with a driver for its RGB LED:
leds-an30259a.c. I am adjusting that driver to LED multicolor class
and I will have certainly some more remarks (also to the variable naming
I proposed myself, which after few months feels awkward to me).

Generally speaking - we have to do everything to make the addition
of LED multicolor support to the driver way easier and more
straightforward since currently it is painful. I would go for
a separate compilation unit for multicolor specifc part of LED drivers.
But I will be able to tell more after few more days.
