From 6285bd151b95aa28d6de9b8b9249702681f059d2 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Thu, 21 Mar 2019 10:31:22 +0800 Subject: [PATCH] perf cs-etm: Return errcode in cs_etm__process_auxtrace_info() The 'err' variable is set in the error path, but it's not returned to callers. Don't always return -EINVAL, return err.
