From: Qiushi Wu <wu000273@xxxxxxx>
commit 6e6c25283dff866308c87b49434c7dbad4774cc0 upstream.
kobject_init_and_add() takes reference even when it fails.
Thus, when kobject_init_and_add() returns an error,
kobject_put() must be called to properly clean up the kobject.
Fixes: 3f8055c35836 ("ACPI / hotplug: Introduce user space interface for hotplug profiles")
