API compliance scanning with coccinelle flagged: ./net/irda/timer.c:63:35-37: use of msecs_to_jiffies probably perferable Converting milliseconds to jiffies by "val * HZ / 1000" technically is not a clean solution as it does not handle all corner cases correctly. By changing the conversion to use msecs_to_jiffies(val) conversion is correct in all cases. Further the () around the arithmetic expression was dropped.
