Subject: [PATCH 06/17] perf sort: Make setup_sorting returns an error code
From: Namhyung Kim <namhyung.kim@....com>
Currently the setup_sorting() is called for parsing sort keys and exits
if it failed to add the sort key. As it's included in libperf it'd be
better returning an error code rather than exiting application inside of
the library.
