From: Qiushi Wu <wu000273@umn.edu> commit 4d8be4bc94f74bb7d096e1c2e44457b530d5a170 upstream. kobject_init_and_add() takes reference even when it fails. If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Previous commit "b8eb718348b8" fixed a similar problem.
