函数名称:handle_edge_irq - edge type IRQ handler*@desc: the interrupt description structure for this irq* Interrupt occures on the falling and/or rising edge of a hardware* signal. The occurrence is latched into the irq controller hardware

函数原型:void handle_edge_irq(struct irq_desc *desc)

返回类型:void

参数:
