The menu governor statistics update function tries to determine the amount of time between entry to low power state and the occurrence of the wakeup event. However, the time measured by the framework includes exit latency on top of the desired value. This exit latency is substracted from the measured value to obtain the desired value. When measured value is not available, the menu governor assumes the wakeup was caused by the timer and the time is equal to remaining timer length. No exit latency should be substracted from this value. This patch prevents the erroneous substraction and clarifies the associated comment. It also removes one intermediate variable that serves no purpose. Signed-off-by: Tuukka Tikkanen <tuukka.tikkanen@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |
