My best shot at this is that before commit d4019f0a92ab ("cpufreq: move freq change notifications to cpufreq core") it was required to invoke cpufreq_notify_transition() on a special CPU. Since it looks like a waste, remove it. Signed-off-by: Sebastian Andrzej Siewior Acked-by: Viresh Kumar Cc: Rafael J.
