Lyude Paul c485e2c97d drm/dp_mst: Refactor pdt setup/teardown, add more locking ... Since we're going to be implementing suspend/resume reprobing very soon, we need to make sure we are extra careful to ensure that our locking actually protects the topology state where we expect it to. Turns out this isn't the case with drm_dp_port_setup_pdt() and drm_dp_port_teardown_pdt(), both of which change port->mstb without grabbing &mgr->lock. Additionally, since most callers of these functions are just using it to teardown the port's previous PDT and setup a new one we can simplify things a bit and combine drm_dp_port_setup_pdt() and drm_dp_port_teardown_pdt() into a single function: drm_dp_port_set_pdt(). This function also handles actually ensuring that we grab the correct locks when we need to modify port->mstb.
