Subject: [PATCH 2/6] irqchip/apple-aic: Fix refcount leak in build_fiq_affinity
Date: Wed, 1 Jun 2022 12:09:26 +0400 [thread overview]
Message-ID: <20220601080930.31005-3-linmq006@gmail.com> (raw)
In-Reply-To: <20220601080930.31005-1-linmq006@gmail.com>
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.
Fixes: a5e8801202b3 ("irqchip/apple-aic: Parse FIQ affinities from device-tree")
