It looks like the following patch already beat this to the punch:

8237e8382498 ("dt-bindings: mfd: Correct the node name of the panel LED")

That patch does not retain the LED's label or rename the parent node to
led-controller, however. The label hardly matters for this example, but
perhaps we still want the parent node change to follow leds-pwm.yaml.
