In order to make changes in the ACPICA code, please submit them to the
upstream ACPICA project on GitHub from where they will be
automatically ported to the Linux kernel when the next upstream ACPICA
release is made.

If you want an ACPICA code change that has already been merged into
upstream ACPICA to be ported to Linux before the next ACPICA release,
please send a Linux patch corresponding to it with a Link tag pointing
to the original ACPICA commit or pull request through which it was
submitted.

Thanks!
