From c796b205b88c775fd220c1a63390bac6a8cdda3f Mon Sep 17 00:00:00 2001 From: Aravind Gopalakrishnan Date: Fri, 23 Jan 2015 12:19:35 -0600 Subject: [PATCH] perf/x86/amd/ibs: Convert force_ibs_eilvt_setup() to void The caller of force_ibs_eilvt_setup() is ibs_eilvt_setup() which does not care about the return values. So mark it void and clean up the return statements.
