Subject: LED driver for the Soekris net5501 board
From: Bjarke Istrup Pedersen <gurligebis@xxxxxxxxxx>
LED driver for the Soekris net5501 board.
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.
