Nouveau does not currently support hot-unplugging, but it still makes sense to switch from drm_dev_unregister() to drm_dev_unplug(). drm_dev_unplug() calls drm_dev_unregister() after marking the device as unplugged, but only after any device critical sections are finished. Since nouveau isn't using drm_dev_enter() and drm_dev_exit(), there are no critical sections so this is nearly functionally equivalent. However, the DRM layer does check to see if the device is unplugged, and if it is returns appropriate error codes. In the future nouveau can add critical sections in order to truly support hot-unplugging.
