Subject: [PATCH 04/20] perf test: event_update: fix memory leak of evlist
Date:   Thu, 15 Jul 2021 18:07:09 +0200
Message-Id: <f7994ad63d248f7645f901132d208fadf9f2b7e4.1626343282.git.rickyman7@gmail.com>

ASan reports a memory leak when running the perf test
"49: Synthesize attr update" caused by evlist not being deleted.

This patch adds the missing evlist__delete and removes the
perf_cpu_map__put since it's already being deleted by evlist__delete.
