Hi Hsin-Yi,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on clk/clk-next]
[cannot apply to arm-soc/for-next xlnx/master linus/master v5.6 next-20200405]
[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]
