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 value due to the very bug/inconsistency that Rafael is fixing in this 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..
