leds-gpio: fix default state handling on OF platforms
commit 0493a4ff10959ff4c8e0d65efee25b7ffd4fa5db upstream.
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.
