[PATCH] LED driver for the Soekris net5501 board.
Bjarke Istrup Pedersen
It is based on the previously submitted code by Alessandro Zummo, but is changed to use the new GPIO driver with 2.6.33, and the driver has been moved to drivers/leds where it belongs.

Thanks, I queued this for sending to Richard.

It should have Alessandro's Signed-off-by: at least.
It perhaps should have his From:, also. Please work out with Alessandro
who should be credited as primary author of this driver.

He's more then welcome to take credit for it, since it is his work
that I've just fixed a few things with.
All that I care for, is that it gets added, so more people can benefit
from it :-)
The signed-off part was generated by git, and I simply forgot to add
Alessandro to it.
Best regards,
Bjarke Istrup Pedersen.
