[ Upstream commit 660ba678f9998aca6db74f2dd912fa5124f0fa31 ]
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 this issue by calling kobject_put().
