SubjectRe: [PATCHv5 3/3] ARM:drm ivip Intel FPGA Video and Image Processing Suite
Hi Ong,

[auto build test WARNING on drm/drm-next]
[also build test WARNING on v4.13-rc4 next-20170804]
[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/Hean-Loong-Ong/Intel-FPGA-VIP-Frame-Buffer-II-drm-driver/20170803-200814
base: git://people.freedesktop.org/~airlied/linux.git drm-next
config: tile-allmodconfig (attached as .config)
