cpuidle: menu: Do not update last_state_idx in menu_select()
It is not necessary to update data->last_state_idx in menu_select() as it only is used in menu_update() which only runs when data->needs_update is set and that is set only when updating data->last_state_idx in menu_reflect(). Accordingly, drop the update of data->last_state_idx from menu_select() and get rid of the (now redundant) "out" label from it. No intentional behavior changes. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Daniel Lezcano <daniel.lezcano@linaro.org>
