[BUG] perf/x86: Intel uncore_pmu_to_box() local variable typo

[Stephane Eranian]

Hi,

I don't understand why the local variable box needs to
be declared static here:

static struct intel_uncore_box *
uncore_pmu_to_box(struct intel_uncore_pmu *pmu, int cpu)
{
        static struct intel_uncore_box *box;

        box = *per_cpu_ptr(pmu->box, cpu);
        if (box)
                return box;
        ....
}
