Submitted as http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=3984/1
This patch fixes an error in the numbering of the disk LEDs on the
Linksys NSLU2. The error crept in because the physical location
of the LEDs has the Disk 2 LED *above* the Disk 1 LED.
Thanks to Gordon Farquharson for reporting this.
