[PATCH 59/77] perf stat: Move 'print_mixed_hw_group_error' to 'struct perf_stat_config'

From: Arnaldo Carvalho de Melo
Date: Wed Sep 05 2018 - 18:09:36 EST


From: Jiri Olsa <jolsa@xxxxxxxxxx>

Move the 'print_mixed_hw_group_error' global variable to 'struct perf_stat_config',
so that it can be passed around and used outside the 'perf stat' command.
