commit d24846a4246b6e61ecbd036880a4adf61681d241 upstream.
kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()：
If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object.
Fix memory leak by calling kobject_put().
