[PATCH 18/20] perf trace: free strings in trace__parse_events_option

From: Riccardo Mancini
Date: Thu Jul 15 2021 - 12:08:18 EST


ASan reports several memory leaks running the perf test
"88: Check open filename arg using perf trace + vfs_getname".
The fourth of these leaks is related to some strings never being freed
in trace__parse_events_option.

This patch adds the missing frees.
