Subject: [PATCH AUTOSEL 4.19 089/671] clk: imx6q: fix refcount leak in imx6q_clocks_init()

From: Yangtao Li <tiny.windzz@...il.com>

[ Upstream commit c9ec1d8fef31b5fc9e90e99f9bd685db5caa7c5e ]

The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.
