I think we could avoid this additional argument 'cpumask'. I have
checked the cpufreq_cpu_get function, which should do be good for this:

---------->8-------------------------
static int _get_sharing_cpus(struct device *cpu_dev, struct cpumask *span)
{
        struct cpufreq_policy *policy;

        policy = cpufreq_cpu_get(cpu_dev->id);
        if (policy) {
                cpumask_copy(span, policy->cpus);

That should be with 'policy->related_cpus', but yes if the policy
cpumasks have been populated this approach is OK I think.

                cpufreq_cpu_put(policy);
                return 0;
        } else {
                return -EINVAL;
        }
}
