From 6ec2cf814210fc2df0a59beac895775b6a04d74d Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 9 Oct 2023 20:40:47 +0300 Subject: [PATCH] drm/bridge_connector: stop filtering events in drm_bridge_connector_hpd_cb() 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.
