Subject: [PATCH] clk: tegra: Fix refcount leak in tegra114_clock_init
Date: Mon, 23 May 2022 18:38:34 +0400	[thread overview]
Message-ID: <20220523143834.7587-1-linmq006@gmail.com> (raw)

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.

Fixes: 2cb5efefd6f7 ("clk: tegra: Implement clocks for Tegra114")
