[PULL 1/3] tests/unit/test-smp-parse: Restore MachineClass fields after


From: Philippe Mathieu-Daudé
Subject: [PULL 1/3] tests/unit/test-smp-parse: Restore MachineClass fields after modifying
Date: Mon, 15 Nov 2021 23:48:00 +0100

There is a single MachineClass object, registered with
type_register_static(&smp_machine_info). Since the same
object is used multiple times (an MachineState object
is instantiated in both test_generic and test_with_dies),
we should restore its internal state after modifying for
the test purpose.
