How do I comply with the LED label warnings?
I am not sure about the proper convention. I was assuming led-<name> is correct.
The first two warnings can be fixed by dropping the '-' in the regex.
But I don't see how the last warning should comply with a proper LED node name. 
Or can this be ignored?

OK, thanks for pointing it out. I will add it in v3.
