Hi all,
I agree with Sjoerd, that's more useful to keep these LEDs in sync
with the default vendor behaviour than put their default state to off
and ask the user to manipulate them explicitly... in the worst case,
he can still change the default state from sysfs...

Well, lack of inspiration :P
No, just kidding, I agree.

I used the schematic and the vendor devicetree to retrieve these informations.

Please do.
Do you want a v2 patch ? (the label of these leds is wrong)
