Subject: [PATCH] ARM: zynq: Fix refcount leak in zynq_early_slcr_init
Date: Tue, 29 Nov 2022 22:05:44 +0800 [thread overview]
Message-ID: <20221129140544.41293-1-linqiheng@huawei.com> (raw)
of_find_compatible_node() returns a node pointer with refcount incremented,
we should use of_node_put() on error path.
Add missing of_node_put() to avoid refcount leak.
Fixes: 3329659df030 ("ARM: zynq: Simplify SLCR initialization")
