But lsmod shows 0 for the cpufreq driver right? (Note, your related_cpus
should have only 1 CPU each, for you to see 0. Else, you'll see a non-zero

patch).

I have hacked the driver this way:

@@ -2114,10 +2114,16 @@ int cpufreq_register_driver(struct

cpufreq_driver *driver_data)
        cpufreq_driver = driver_data;
        write_unlock_irqrestore(&cpufreq_driver_lock, flags);

+       printk(KERN_INFO "%s: Module refcount: %lu\n", __func__,
+                       module_refcount(cpufreq_driver->owner));
+
        ret = subsys_interface_register(&cpufreq_interface);
        if (ret)
                goto err_null_driver;


And this gave me 1..
