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.
