[PATCH 11/22] perf tools: Rename and move pmu_event_name to get_config_name

From: Arnaldo Carvalho de Melo
Date: Fri Feb 19 2016 - 17:45:25 EST


From: Wang Nan <wangnan0@xxxxxxxxxx>

Following commits will make more events obey /name=newname/ options.
This patch makes pmu_event_name() a generic helper.

Makes new get_config_name() accept NULL input to make life easier.
