But after the external device is plugged-out, the EDID property is not updated. In such case we still get the corresponding EDID property although it is already detected as disconnected. https://bugs.freedesktop.org/show_bug.cgi?id=26743 Signed-off-by: Zhao Yakui Signed-off-by: Zhenyu Wang Cc: stable@kernel.org Signed-off-by: Dave Airlie --- diff --git a/drivers/gpu/drm/drm_crtc_helper.c b/drivers/gpu/drm/drm_crtc_helper.c index f2aaf39be398..51103aa469f8 100644 --- a/drivers/gpu/drm/drm_crtc_helper.c +++ b/drivers/gpu/drm/drm_crtc_helper.c @@ -104,6 +104,7 @@ int drm_helper_probe_single_connector_modes(struct drm_connector *connector, if (connector->status == connector_status_disconnected) { DRM_DEBUG_KMS("%s is disconnected\n", drm_get_connector_name(connector)); + drm_mode_connector_update_edid_property(connector, NULL); goto prune; }
