This patch description is used in ACPICA upstream.
For ACPICA code base, __FUNCTION__ is only used for its MSVC builds.
And __func__ is converted from __FUNCTION__ by the linuxize release script.

See the original commit here:
https://github.com/acpica/acpica/commit/cb3d1c79

So this is simply an automated release output.
Without this merged, source code differences between Linux upstream and ACPICA upstream will hurt the automation.

Thanks and best regards
