    [ARM] Orion: top-level IRQs are level-triggered · 000e99c3
    Lennert Buytenhek 提交于
    Make it clear that Orion top-level IRQs are level-triggered.  This
    means that we don't need an ->ack() handler, or at least, we don't
    need the ->ack() handler (or the acking part of the ->mask_ack()
    handler) to actually do anything.
    
    Given that, we might as well point our ->mask_ack() handler at the
    ->mask() handler instead of providing a dummy ->ack() handler, since
    providing a ->mask_ack() handler on level IRQ sources will prevent
    ->ack() from ever being called.
