From: Ilkka Koskinen <ilkka@xxxxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 90fe70d4e23cb57253d2668a171d5695c332deb7 ]
AmpereOne metrics were missing DefaultMetricgroupName from metrics with
"Default" in group name resulting perf to segfault. Add the missing
field to address the issue.
Fixes: 59faeaf80d02 ("perf vendor events arm64: Fix for AmpereOne metrics")
