Here are 80 character problems:

1.        pit_clockevent.mult = div_sc(CLOCK_TICK_RATE, NSEC_PER_SEC,
                                     pit_clockevent.shift);
2.        pit_clockevent.max_delta_ns =
                clockevent_delta2ns(0x7FFF, &pit_clockevent);
3.        pit_clockevent.min_delta_ns =
                clockevent_delta2ns(0xF, &pit_clockevent);

4.        clocksource_pit.mult = clocksource_hz2mult(CLOCK_TICK_RATE,
                                                   clocksource_pit.shift);
