[PATCH 3.16 007/129] clk: imx6q: fix refcount leak in imx6q_clocks_init()

[Ben Hutchings]

3.16.70-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Yangtao Li <tiny.windzz@xxxxxxxxx>

commit c9ec1d8fef31b5fc9e90e99f9bd685db5caa7c5e upstream.

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.
