[PATCH 1/9] perf tools: Pass evsel to hpp->header/width functions explicitly

From: Namhyung Kim
Date: Mon Mar 10 2014 - 03:44:16 EST


Those functions need evsel to investigate event group and it's passed
via hpp->ptr. However as it can be missed easily so it's better to
pass it via an argument IMHO.
