Subject: Re: [PATCH v3] gpio: winbond: add driver

Hi Maciej,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on gpio/for-next]
[also build test ERROR on v4.15-rc6 next-20180102]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
