From 8079876497653381c233445374465c3da6450766 Mon Sep 17 00:00:00 2001 From: Sukadev Bhattiprolu Date: Mon, 30 Mar 2015 18:53:41 -0700 Subject: [PATCH] powerpc/perf/hv-24x7: Drop event_24x7_request() The function event_24x7_request() is essentially a wrapper to the function single_24x7_request() and can be dropped to simplify code.
