+Subject: irqchip/gic/realview: Fix refcount leak in realview_gic_of_init
+
+From: Miaoqian Lin <linmq006@gmail.com>
+
+[ Upstream commit f4b98e314888cc51486421bcf6d52852452ea48b ]
+
+of_find_matching_node_and_match() 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: 82b0a434b436 ("irqchip/gic/realview: Support more RealView DCC variants")
