NACK.
This GPIO line is not connected to any LED, it does not even control anything on
the other devices from the M series.
Additionally, you can use the sysfs interface to control the GPIO line without
any patch:
echo 8 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio8/direction
echo 1 > /sys/class/gpio/gpio8/value
