From 5aed213c7c6c4f5dcb1a3ef146f493f18fe703dc Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann tzimmermann@suse.de Date: Fri, 10 May 2024 17:47:08 +0200 Subject: [PATCH] drm/udl: Remove DRM_CONNECTOR_POLL_HPD

DisplayLink devices do not generate hotplug events. Remove the poll flag DRM_CONNECTOR_POLL_HPD, as it may not be specified together with DRM_CONNECTOR_POLL_CONNECT or DRM_CONNECTOR_POLL_DISCONNECT.
