SubjectRe: [PATCH v11 3/3] fpga: Add support for Lattice iCE40 FPGAs
Hi Joel,

[auto build test WARNING on next-20170106]
[also build test WARNING on v4.10-rc3]
[cannot apply to linus/master linux/master robh/for-next v4.9-rc8 v4.9-rc7 v4.9-rc6]
[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/Joel-Holdsworth/of-Add-vendor-prefix-for-Lattice-Semiconductor/20170109-134955
config: ia64-allmodconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 6.2.0
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
