>> The leds-gpio driver recently switched to the device property API. The device_node
>> name is no longer retrieved if the "label" devicetree property is not found.
>> In this case the driver tries to create entries with (null) name in
>> /sys/class/leds, which is wrong and generates backtrace as several gpio_leds have
>> the same name. Also renamed subnode "yellow" to "blue" to match the last
>> schematics updates.
