Cover letter [PATCH 0/4] Unregister mst connectors when hotplug
By patches below, we change to clean up resources of a mst connector and put port's malloc_kref when we start to destroy a connector.
* 09b974e8983 drm/amd/amdgpu_dm/mst: Remove ->destroy_connector() callback
* 72dc0f51591 drm/dp_mst: Remove drm_dp_mst_topology_cbs.destroy_connector
However, find out that mst connectors won't reach connector destroy flow after hot unplug and hence will cause no more resources for new added connectors. Thus, this patch set is trying to solve observed registration/unregistration problem of mst connectors.
