Subject: [PATCH v6 4/7] perf test: Fix matching_pmu
Date:   Mon,  7 Aug 2023 15:51:22 +0800
Message-Id: <1691394685-61240-5-git-send-email-renyu.zj@linux.alibaba.com>
In-Reply-To: <1691394685-61240-1-git-send-email-renyu.zj@linux.alibaba.com>
References: <1691394685-61240-1-git-send-email-renyu.zj@linux.alibaba.com>
Precedence: bulk

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")
