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")

Is this tag correct, as I was not sure if this ever worked?

BTW, I am not sure how useful fixes tags are for self-test anyway...

I added the tag with reference to the previous fixed patch, and it seems correct.

I'm not sure if it's useful either, but I added it anyway.:)
