building into a module
Hi Baolin,
I love your patch! Yet something to improve:
[auto build test ERROR on pinctrl/devel]
[also build test ERROR on v5.6-rc3 next-20200228]
[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]
