When a uevent only updates a single connector, add a CONNECTOR property to the uevent. This allows user-space to ignore other connectors when handling the uevent. This is purely an optimization, drivers can still send a uevent without the CONNECTOR property. The CONNECTOR property is already set when sending HDCP property update uevents, see drm_sysfs_connector_status_event. This has been tested with a wlroots patch [1]. amdgpu has been updated to use these new fine-grained uevents.
