Ok, this is somehow unusual/crazy. Single driver with two interfaces.
Do we need the LED interface for something?
If yes, I believe reasonable solution would be to always provide LED
interface, and then have "backlight-trigger" which that would provide
backlight interface for arbitrary LED.
Thanks,
Pavel
