Subject: [PATCH 4.14 119/210] clk: tegra: Fix refcount leak in tegra114_clock_init
From: Miaoqian Lin <linmq006@...il.com>
[ Upstream commit db16a80c76ea395766913082b1e3f939dde29b2c ]
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")
