You don't really need to have any special code here, specially for the case that
may never get hit. For example, if we fail to initialize something for CPU0,
cpufreq core will try calling this routine for other CPUs as well. I don't think
there is anything wrong in letting cpufreq core trying that. Why stop it or
return early? It wouldn't happen normally, unless there is a bug in there.
