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.
