When building this driver as a module, we get a helpful warning about the return type: drivers/cpufreq/integrator-cpufreq.c:232:2: warning: initialization from incompatible pointer type .remove = __exit_p(integrator_cpufreq_remove), If the remove callback returns void, the caller gets an undefined value as it expects an integer to be returned. This fixes the problem by passing down the value from cpufreq_unregister_driver.
