arc: fix use of uninitialized arc_pmu
static arc_pmu in the arch/arc/kernel/perf_event.c is not initialized as it's shadowed by a local variable of the same name in the arc_pmu_device_probe. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Fixes: 03c94fcf954d "ARC: perf: make @arc_pmu static global" CC: <stable@vger.kernel.org> # 4.1 Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
