Is there an upstream ACPICA commit for this?
There is a PR for it now.

	https://github.com/acpica/acpica/pull/976

Do I need to reference that in this patch?  Or wait for it to be merged
and drop this hunk?

Wait for it to be merged first.  Then either drop this hunk and wait for an ACPICA release (that may not happen soon, though), or send a Linux patch corresponding to it with a Link tag pointing to the above.

Thanks!
