[ Upstream commit 4ddf4739be6e375116c375f0a68bf3893ffcee21 ]
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.
