Subject: [PATCH] clk: samsung: exynos4: fix refcount leak in exynos4_get_xom()
Git-commit: cee82eb9532090cd1dc953e845d71f9b1445c84e
Patch-mainline: v5.1-rc1
References: bsc#1051510

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.
