[CPUFREQ] ondemand: trivial clean-ups
Trivial ondemand governor clean-ups: - change from sampling_rate_in_HZ() to the official function usecs_to_jiffies(). - use for_each_online_cpu() to instead of using "if (cpu_online(i))" Signed-off-by: Eric Piel <eric.piel@tremplin-utc.net> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Dave Jones <davej@redhat.com>
