[PATCH v6 4/7] perf test: Fix matching_pmu

From: Jing Zhang
Date: Mon Aug 07 2023 - 03:52:48 EST


The perf_pmu_test_event.matching_pmu didn't work. No matter what its
value is, it does not affect the test results. So let matching_pmu be
used for matching perf_pmu_test_pmu.pmu.name.

Fixes: 5a65c0c8f6fd ("perf test: Re-add pmu-event uncore PMU alias test")
