Subject: [PATCH] clk: tegra: Fix refcount leak in tegra114_clock_init
Date:   Mon, 23 May 2022 18:38:34 +0400
Message-Id: <20220523143834.7587-1-linmq006@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

of_find_matching_node() 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.
