leds-gpio: fix default state handling on OF platforms
The driver wrongly sets default state for LEDs that don't specify default-state property. Currently the driver handles default state this way: memset(&led, 0, sizeof(led)); for_each_child_of_node(np, child) { state = of_get_property(child, "default-state", NULL); if (state) { if (!strcmp(state, "keep")) led.default_state = LEDS_GPIO_DEFSTATE_KEEP; ... } ret = create_gpio_led(&led, ...); } Which means that all LEDs that do not specify default-state will inherit the last value of the default-state property, which is wrong. This patch fixes the issue by moving LED's template initialization into the loop body.
