## Description

In the Linux kernel, the following vulnerability has been resolved:  rapidio: rio: fix possible name leak in rio_register_mport()  If device_register() returns error, the name allocated by dev_set_name() need be freed.  It should use put_device() to give up the reference in the error path, so that the name can be freed in kobject_cleanup(), and list_del() is called to delete the port from rio_mports.
