José Roberto de Souza 8ccb5bf761 drm/mst: Fix possible NULL pointer dereference in drm_dp_mst_process_up_req() ... According to DP specification, DP_SINK_EVENT_NOTIFY is also a broadcast message but as this function only handles DP_CONNECTION_STATUS_NOTIFY I will only make the static analyzer that caught this issue happy by not calling drm_dp_get_mst_branch_device_by_guid() with a NULL guid, causing drm_dp_mst_process_up_req() to return in the "if (!mstb)" right bellow.
