drm: Remove drm dp mst destroy_connector callbacks
drm_dp_mst_topology_mgr_cbs.destroy_connector callbacks are identical amongst every driver and don't do anything other than cleaning up the connector((drm_connector_unregister()/drm_connector_put())) except for amdgpu_dm driver where some amdgpu_dm specific code in there. This connector cleaning up is now being handled in the drm core so driver destroy_connector callbacks are not needed (except for amdgpu_dm) hence remove them. Removal is done with below sementic patch: @r1@ identifier func, E; @@ struct drm_dp_mst_topology_cbs E = { ..., - .destroy_connector = func }; @delete depends on r1@ identifier r1.func; @@ - static void func(...){...} Signed-off-by: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com> Suggested-by: Emil Velikov <emil.velikov@collabora.com> Suggested-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200307083023.76498-6-pankaj.laxminarayan.bharadiya@intel.comReviewed-by: Lyude Paul <lyude@redhat.com>
