From ba3df9792207601762060a313d18efdd6ae83501 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 13 Nov 2014 14:54:01 +0100 Subject: [PATCH] drm/tegra: dsi: Mark connector hotpluggable DSI panels can always be hotplugged via the DSI bus' attach/detach infrastructure, so unconditionally mark the connector hotpluggable. While at it, also make sure that when a panel is detached the connector is marked unconnected before calling into the DRM hotplug helpers to reflect the correct state.
