+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.
