OK, I will post v2 patch to solve this issue. But it will be after patch-review.

[auto build test WARNING on robh/for-next] [also build test WARNING on v4.7-rc4 next-20160623] [cannot apply to glikely/devicetree/next] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
