Subject: [PATCH] perf tracepoint: Fix memory leak in is_valid_tracepoint()
References: bsc#1012628
Patch-mainline: 6.3.3
Git-commit: 9b86c49710eec7b4fbb78a0232b2dd0972a2b576

[ Upstream commit 9b86c49710eec7b4fbb78a0232b2dd0972a2b576 ]

When is_valid_tracepoint() returns 1, need to call put_events_file() to
free `dir_path`.

Fixes: 25a7d914274de386 ("perf parse-events: Use get/put_events_file()")
