Please add a pr_debug() here, that will be quite useful while debugging.

Also, you can't simply pass 0 to get_table() above. We might be
registering the cooling device for some other cluster as well..

This is what I have done in my patch earlier.

cpufreq_frequency_get_table(cpumask_first(clip_cpus));

And this will work for all cases.
