Normally nothing - in most systems the interrupt will not be shared
and/or the board irq_enable() operation will completely disable the IRQ
line.  The main use case would be if the interrupt is shared and the
board irq_enable() operation doesn't affect other sources, though boards
may also decide that they can do without disabling the interrupt.
