irqchip/apple-aic: Fix refcount leak in build_fiq_affinity
漏洞描述信息
In the Linux kernel, the following vulnerability has been resolved:
irqchip/apple-aic: Fix refcount leak in build_fiq_affinity
of_find_node_by_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
