Sun Mar 25 10:17:56 PDT 2018 

Hi Manivannan,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on robh/for-next]
[also build test ERROR on v4.16-rc6]
[cannot apply to clk/clk-next next-20180323]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
