From: Qiushi Wu <wu000273@umn.edu>
kobject_init_and_add() should be handled when it return an error, because 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. Thus replace calling kfree() by calling kobject_put().
