void free_irq (unsigned int irq, void * dev_id);
irq Interrupt line to free

Remove an interrupt handler. The handler is removed and if the
interrupt line is no longer in use by any driver it is disabled. On a
shared IRQ the caller must ensure the interrupt is disabled on the card
it drives before calling this function. The function does not return
until any executing interrupts for this IRQ have completed.
This function must not be called from interrupt context.
