[PATCH 43/77] perf stat: Pass 'struct perf_stat_config' argument to local print functions

From: Arnaldo Carvalho de Melo
Date: Wed Sep 05 2018 - 18:06:53 EST

From: Jiri Olsa <jolsa@xxxxxxxxxx>

Add 'struct perf_stat_config' argument to print functions, so that those
functions can be moved out of the 'perf stat' command to a generic class
in the following patches.
