The IRQ pin will go from high to low when the irq bit is clear. To let the IRQ pin go low as early as possible, move the clear irq bit function to the beginning of irq handler.
Why is this a benefit? We're going to mask the interrupt as long as the interrupt handler is running anyway.
Thanks for your reminding. There is actually no benefit on the patch. Can you ignore this patch and apply other two patches? Or I should send the patches again?
