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. Signed-off-by: Rod Whitby <rod@whitby.id.au> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
