[PATCH 3.16 006/129] clk: samsung: exynos4: fix refcount leak in exynos4_get_xom()

[Ben Hutchings]

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

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

From: Yangtao Li <tiny.win...@gmail.com>

commit cee82eb9532090cd1dc953e845d71f9b1445c84e 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.
