Note that we have already two LED flash class drivers - leds-max77693
and leds-aat1290. They have been present in mainline for over two years
now.

I'd rather avoid overcomplicating this. LED class device name pattern
is well defined to devicename:colour:function
(see Documentation/leds/leds-class.txt, "LED Device Naming" section).

In this case "flash" in place of the "function" segment makes the
things clear enough I suppose.
