[ Upstream commit 3d45670fab3c25a7452721e4588cc95c51cda134 ]
of_get_child_by_name() 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.
Fixes: a5e8801202b3 ("irqchip/apple-aic: Parse FIQ affinities from device-tree")
