From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> In some cases the bridge drivers would like to receive hotplug events even in the case new status is equal to the old status. In the DP case this is used to deliver "attention" messages to the DP host. Stop filtering the events in the drm_bridge_connector_hpd_cb() and let drivers decide whether they would like to receive the event or not.
