Before I patch the kernel, what is the difference between the mentioned driver and the driver found in
http://lxr.linux.no/#linux+v2.6.32.28/drivers/char/cs5535_gpio.c

And there are two drivers in latest 2.6.37 too...
http://lxr.linux.no/#linux+v2.6.37/drivers/char/cs5535_gpio.c
http://lxr.linux.no/#linux+v2.6.37/drivers/gpio/cs5535-gpio.c

Why not using the stock one but instead of this patch?
