Subject: [PATCH] ARM: highbank: Fix refcount leak in highbank_init
Date:   Thu, 12 May 2022 07:12:58 +0400
Message-Id: <20220512031259.56459-1-linmq006@gmail.com>

of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: 220e6cf7b793 ("ARM: add Highbank core platform support")
