Subject: [PATCH 4.9 029/271] clk: samsung: exynos4: fix refcount leak in exynos4_get_xom()
From: Yangtao Li <tiny.windzz@...il.com>
[ Upstream commit cee82eb9532090cd1dc953e845d71f9b1445c84e ]
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.
