Why can't this driver use the existing gpio-led driver?  Basically, do
something like this:

of_gpio_leds_probe(...)
{
 	gpio = of_get_gpio(np, 0);
 	label = of_get_property(np, "label", NULL);

 	struct gpio_led led = {
 		.name = label,
 		.gpio = gpio,
 	};

 	pdev = platform_device_register_simple("leds-gpio", 0, NULL, 0);
 	platform_device_add_data(pdev, &led, sizeof(led));
}
