From: Namhyung Kim Date: Tue, 19 May 2015 08:04:10 +0000 (+0900) Subject: perf hists: Reducing arguments of hist_entry_iter__add() X-Git-Tag: v4.14-rc1~5252^2~20^2~19 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=063bd9363bb8979b2939bdc0412d98a8ac062e3b;p=platform%2Fkernel%2Flinux-rpi.git perf hists: Reducing arguments of hist_entry_iter__add() The evsel and sample arguments are to set iter for later use. As it also receives an iter as another argument, just set them before calling the function.
