Subject: [PATCH] irqchip/gic/realview: Fix refcount leak in realview_gic_of_init
Date: Thu, 26 May 2022 11:43:48 +0400 [thread overview]
Message-ID: <20220526074348.23972-1-linmq006@gmail.com> (raw)
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")
