Subject: Re: [PATCH v2 03/11] media: rkisp1: add rockchip isp1 driver

Hi Jacob,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on linuxtv-media/master]
[also build test ERROR on next-20171124]
[cannot apply to rockchip/for-next v4.14]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
