But a separate patch caused kdev lifetime changes: commit 5bdebb183c9702a8c57a01dff09337be3de337a6 Author: Dave Airlie Date: Fri Oct 11 14:07:25 2013 +1000 drm/sysfs: sort out minor and connector device object lifetimes. Thus making our dev_is_registered() call useles (and even segfault if it is NULL). Replace it with a simple !kdev test and we're fine.
