Hi Maxime,

Thank you for the patch.

Please don't use the word "current", it's ambiguous. Do you mean old
state or new state ?

Is this relevant ? drm_atomic_helper_swap_state() doesn't change the
old_state and new_state pointers in drm_atomic_state as far as I can
tell.

This seems to imply that you're interested in the new state.

Does this really make things more obvious ?
