As Rob suggested, adding the word "typically" would resolve my claim.

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Labels cannot contain '-'.

I'll make this

        sunrise: co2-sensor@68

My bad and sorry for not running dt_binding_check, I thought the
changes were trivial enough.

Thanks

Why label at all?  Might be handy on a real board, but example doesn't need it.
