Unlike a normal IRQ, a multilevel IRQ can't be incremented by simply `irq++`, as that would always increment the L1 of a IRQ, regardless of its level. A function that understands the level for which the IRQ operates in is required. Signed-off-by: Yong Cong Sin <ycsin@meta.com> Signed-off-by: Yong Cong Sin <yongcong.sin@gmail.com>
