The next goto after that is messed up as well:

  1056          dev = nfc_get_device(idx);
  1057          if (!dev)
  1058                  return -ENODEV;
  1059  
  1060          device_lock(&dev->dev);
  1061  
  1062          local = nfc_llcp_find_local(dev);
  1063          if (!local) {
  1064                  nfc_put_device(dev);

It should not call nfc_put_device() because that happens after goto
exit.

  1065                  rc = -ENODEV;
  1066                  goto exit;
  1067          }
