Hi Sascha,

Thanks, this works well for my board. (tri colour led).

Was drivers/led/led-triggers.c missing from the patch set? 
I haven't been able to compile with trigger support...

How about being able to register a led at a specific number? This means that 
boot/init scripts that want to interact with leds don't rely on the order that 
they are registered.

I also like the suggestion of associating a name to LEDs. This may even be a 
better fit for scripting than reserved numbering.

Spelling typo? (Should this be trigger ?)
