If get_1284_register()\nfails, the error path drops the driver private data and the USB device\nreference, but leaves the parport device registered.\n\nLeaving the port registered is more than a private allocation leak:\nparport_register_port() has already reserved a parport number and\nregistered the parport bus device, while pp->private_data still points at\nthe private data that the common error path is about to release.\n\nUndo the pre-announce registration in the get_1284_register() failure\nbranch before jumping to the common private-data cleanup path. Clear\npriv->pp first, matching the disconnect path and avoiding a stale pointer\nin the private data.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel
