[PATCH 5/7] perf diff: Get rid of hists__compute_resort()

From: Namhyung Kim
Date: Sun Dec 21 2014 - 23:44:09 EST


The hists__compute_resort() is to sort output fields based on the
given field/criteria. This was done without the sort list but as we
added the field to the sort list, we can do it with normal
hists__output_resort() using the ->sort callback.
