From: Sanskriti Sharma <sansh...@redhat.com> For each system in a given pevent, read_event_files() reads in a temporary 'sys' string. Be sure to free this string before moving onto to the next system and/or leaving read_event_files().
Fixes the following coverity complaints: Error: RESOURCE_LEAK (CWE-772): tools/perf/util/trace-event-read.c:343: overwrite_var: Overwriting "sys" in "sys = read_string()" leaks the storage that "sys" points to. tools/perf/util/trace-event-read.c:353: leaked_storage: Variable "sys" going out of scope leaks the storage it points to.
