From 2f47f1c106d99f367f2924ce35741050fb87e081 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 5 Sep 2017 14:10:17 +0200 Subject: [PATCH] drm/bridge: adv7511: Enable connector polling when no interrupt is specified Fall back to polling the connector for connect and disconnect events when no interrupt is specified. Otherwise these events will not be noticed and monitor hotplug does not work.
