handle_simple_irq - Simple and software-decoded IRQs.

void handle_simple_irq(unsigned int  irq , struct irq_desc *  desc );

irq
    the interrupt number

desc
    the interrupt description structure for this irq

Simple interrupts are either sent from a demultiplexing interrupt handler or come from hardware, where no interrupt hardware control is necessary.

The caller is expected to handle the ack, clear, mask and unmask issues if necessary.
