From: Xiaogang Chen xiaogang.chen@amd.com
drm_dp_check_and_send_link_address discovers MST device topology. It can return both positive and negative values. When it returns positive values there is no error found. If it returns negative values there is error found, such as get NAK , timeout, etc. Following drm_kms_helper_hotplug_event should be called when drm_dp_check_and_send_link_address returns positive value.
