The current code uses a device-managed function to retrieve the next bridge
downstream.
However, that means that it will be removed at unbind time, where the DRM
device is still very much live and might still have some applications that
still have it open.
Switch to a DRM-managed variant to clean everything up once the DRM device
has been last closed.
