Either wait for the binding to be applied or apply the binding with
this if it is a binding only change with no driver changes so that we
can have fewer intermittent warnings. It didn't help that it was not a
series.

I'm applying the binding.

My bad, I always dtbs_check against the linux-next processed-schema
before pushing out. I'm trying to figure out why that didn't catch this
and the missing Shikra bindings :(

That would have been helpful...
