stable inclusion
from linux-4.19.129
commit 7ba9be0ba0ce951deeaa057bfcf01f2b21a5b89a

--------------------------------

commit d8bd8c6e 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.
