Just an aside: If we want to use drm_obj->state instead of new_config then
we deviate a bit from the helpers: The helpers only apply the new state to
state pointers in ->commit, we have our ->new_config pointer already set
in the compute/check config phase. Essentially it's not the same thing.

Now with the drm core you can just look up any state object you need, but
that'll lead to a bit more cumbersome code maybe. Otoh if we keep using
->new_config we need those in our ->atomic_check and then reapply in
->atomic_commit.

I'm ok with either approach really, so will leave it to you.
