Hi,

is there the possibility we could make dtschema as invoked by `make 
dt_binding_check W=1` (or W=2) add a warning for examples that have disabled 
or explicitly listed status properties when not needed? Or is this something 
better handled in, say, checkpatch.pl?

The question arises because dumb mistakes by me like this should ideally be 
caught before they waste precious maintainer time.

If it's best handled in dtschema, I can look into working on that so you guys 
don't have to do even more work due to me.

Cheers,
Nicolas Frattaroli
