Function compare_pmu_events() does not compare all struct pmu-events members, so add tests for missing members "name", "event", "aggr_mod", "event", "metric_constraint", and "metric_group", and re-order the tests to match current struct pmu-events member ordering. Also fix uncore_hisi_l3c_rd_hit_cpipe.event member, now that we're actually testing it. Signed-off-by: John Garry <redacted>
Acked-by: Ian Rogers <irogers@google.com> Thanks, Ian
