Oh, didn't realize that you're sharing config->prop_crtc_id with plane and
connector. Please add a comment about that to drm_crtc.h.
Plus same comment about setting DRM_MODE_PROB_ATOMIC. With these two this
is Reviewed-by: Daniel Vetter <daniel.vetter@xxxxxxxx>
I wasn't to clear in my reply to the previous patch probably, but I think
the atomic filtering should be in an earlier patch. Best in the missing
one to add the modparam and file_priv->atomic_kms.
