Lyude Paul dbc05ae386 drm/dp_mst: Fix drm_dp_send_dpcd_write() return code ... drm_dp_mst_wait_tx_reply() returns > 1 if time elapsed in wait_event_timeout() before check_txmsg_state(mgr, txmsg) evaluated to true. However, we make the mistake of returning this time from drm_dp_send_dpcd_write() on success instead of returning the number of bytes written - causing spontaneous failures during link probing: [drm:drm_dp_send_link_address [drm_kms_helper]] *ERROR* GUID check on 10:01 failed: 3975 Yikes! So, fix this by returning the number of bytes written on success instead.
