If an interrupt keeps coming in and there is no registered handler for that device (for instance, all drivers return IRQ_NONE), then the kernel can block interrupts from that device.
如果一个中断请求不断到来而且没有注册那个设备的处理程序(例如，所有的驱动程序都返回IRQ_NONE)，内核就会忽略来自那个设备的中断。
By default, the driver IRQ routine should return IRQ_HANDLED as it is a bug to return IRQ_NONE when the driver has actually handled that interrupt.
缺省情况下，驱动程序IR Q例程应该返回IRQ_HANDLED，当驱动程序正在处理那个中断时却返回了IRQ_NONE，说明存在bug。
