Subject: cpupower: Correct return type of cpu_power_is_cpu_online() in cpufreq-set

From: Laura Abbott <[email protected]>

commit c25badc9ceb612c6cc227a6fc4b0aaf678e3bcf9 upstream.

When converting to a shared library in ac5a181d065d ("cpupower: Add cpuidle parts into library"), cpu_freq_cpu_exists() was converted to cpupower_is_cpu_online(). cpu_req_cpu_exists() returned 0 on success and -ENOSYS on failure whereas cpupower_is_cpu_online returns 1 on success. Check for the correct return value in cpufreq-set.
