Subject[PATCH 04/10] perf report: Get rid of hist_entry__callchain_fprintf()
Date
From: Namhyung Kim <namhyung@kernel.org>

It's just a wrapper function to align the start position ofcallchains to
'comm' of each thread if it's a first sort key. But it doesn't not work
with tracepoint events and also with upcoming hierarchy view.
