[PATCH 4.9 092/159] clk: tegra: Fix refcount leak in tegra210_clock_init

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit 56c78cb1f00a9dde8cd762131ce8f4c5eb046fbb ]

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: 6b301a059eb2 ("clk: tegra: Add support for Tegra210 clocks")
