From 758f588d6fa2b1e64b6ae4bc4e7e86331bdee479 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Sun, 4 Sep 2016 19:13:57 +0200 Subject: [PATCH] kvm/x86: Fix unused variable warning in kvm_timer_init() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When CONFIG_CPU_FREQ is not set, int cpu is unused and gcc rightfully warns about it: arch/x86/kvm/x86.c: In function ‘kvm_timer_init’: arch/x86/kvm/x86.c:5697:6: warning: unused variable ‘cpu’ [-Wunused-variable] int cpu; ^~~ But since it is used only in the CONFIG_CPU_FREQ block, simply move it there, thus squashing the warning too.
