I can see following in Documentation/devicetree/bindings/leds/leds-gpio.yaml:

 patternProperties:
   # The first form is preferred, but fall back to just 'led' anywhere in the
   # node name to at least catch some child nodes.
   "(^led-[0-9a-f]$|led)":

So it seems like `led-0` is indeed preferred, should I send v2 or a new patch
as a fix on top of the previous one?
