stable inclusion from stable-5.10.54 commit 2bfa3c53ea8a1dc5e485f0b656285048ef106810 bugzilla: 175586 https://gitee.com/openeuler/kernel/issues/I4DVDU
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit da6b7c6c0626901428245f65712385805e42eba6 ]
ASan reports memory leaks while running:
# perf test "83: Zstd perf.data compression/decompression"
The first of the leaks is caused by env->cpu_pmu_caps not being freed.
This patch adds the missing (z)free inside perf_env__exit.
