Why don't you look at it before making such a suggestion? ;) It is in no 
way useful, as I pointed out in my cover letter. The only thing related 
today, as Geert pointed out, is in the input subsystem.

If you don't want this in leds, you'll have to help make leds subsystem 
more useful to external users - the latest function refactoring has been 
anything but helpful here, as you've seen with the indicators, and we're 
completely lacking any indexing or bulk operations on the LED controller 
level, since you treat each LED as a standalone device. That's precisely 
why this code is here in leds although - as I pointed out - it shouldn't 
belong here.

Regards,
Andreas
