Tetsuo Handa a6d84e51ab can: j1939: j1939_local_ecu_get(): undo increment when j1939_local_ecu_get() fails ... [ Upstream commit 06e02da29f6f1a45fc07bd60c7eaf172dc21e334 ] Since j1939_sk_bind() and j1939_sk_release() call j1939_local_ecu_put() when J1939_SOCK_BOUND was already set, but the error handling path for j1939_sk_bind() will not set J1939_SOCK_BOUND when j1939_local_ecu_get() fails, j1939_local_ecu_get() needs to undo priv->ents[sa].nusers++ when j1939_local_ecu_get() returns an error.
