Ben Dai 0c8dea3fd5 genirq/timings: Prevent potential array overflow in __irq_timings_store() ... commit b9cc7d8a4656a6e815852c27ab50365009cb69c1 upstream. When the interrupt interval is greater than 2 ^ PREDICTION_BUFFER_SIZE * PREDICTION_FACTOR us and less than 1s, the calculated index will be greater than the length of irqs->ema_time[]. Check the calculated index before using it to prevent array overflow.
