3.14-stable review patch. If anyone has any objections, please let me know.

From: Krzysztof Kozlowski <k.kozlowski@samsung.com>
commit 238e14055da87d0d012257788e39fe0df3a82226 upstream.
If parent device does not have of_node set the s2mps11_clk_parse_dt() returned NULL. This NULL was later passed to of_clk_add_provider() which dereferenced it in pr_debug() call.
