Hi Vivek,

[auto build test WARNING on balbi-usb/next]

[cannot apply to pza/reset/next]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Vivek-Gautam/reset-APIs-to-manage-a-list-of-resets/20170404-111639

All warnings (new ones prefixed by >>):
