+Subject: efi/efivars: Add missing kobject_put() in sysfs entry creation error path
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+From: Ard Biesheuvel <ardb@kernel.org>
+
+commit d8bd8c6e2cfab8b78b537715255be8d7557791c0 upstream.
+
+The documentation provided by kobject_init_and_add() clearly spells out
+the need to call kobject_put() on the kobject if an error is returned.
+Add this missing call to the error path.
