ACPICA code comes from an external project. The proper way of
modifying it is to submit a pull request to the upstream ACPICA
project on GitHub. Once this pull request has been merged upstream, a
Linux patch containing a Link: tag to the corresponding upstream pull
request can be submitted.
Thanks!
