I'll keep ignoring the patch until someone will figure out how to make new way
of handling LEDs play well with the current way (via writing to evdev). That
means not treating access to evdev as "raw" and ignoring LED trigger remapping
done in LED layer. So far I just heard that it is not a problem and nobody uses
evdev interface...

Thanks.
