Hi Rahul, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on clk/clk-next] [also build test WARNING on robh/for-next v5.5-rc3 next-20191220] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url:
