drm/i915: Make sure all planes and connectors are added on modeset.
Browse files Browse the repository at this point in the history
Add missing calls to drm_atomic_add_affected_*. This is needed
to convert to atomic planes. When converting to atomic all planes
are needed on modeset. For good measure make sure all connectors
are added too.
