[ Upstream commit 8623ccbfc55d962e19a3537652803676ad7acb90 ]
If device_register() returns error, the name allocated by dev_set_name() need be freed. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanup(), and client_dev is freed in ntb_transport_client_release().
