[Qemu-devel] [PATCH 3/3] acpi unit-test: do not fail on asl mismatch

[Marcel Apfelbaum <marcel.a@redhat.com>]

The asl comparison will break every time the ACPI
tables are updated. This may break the git bisect.
Instead of failing print a warning on stderr
including the retained asl files, so they can be
compared offline.
