SubjectRe: [PATCH 11/16] fpga: intel: fme: add partial reconfiguration sub feature support
Hi Kang,

[auto build test WARNING on linus/master]
[also build test WARNING on v4.11-rc4 next-20170331]
[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/Wu-Hao/Intel-FPGA-Device-Drivers/20170401-052017
config: sparc-allyesconfig (attached as .config)
compiler: sparc64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=sparc
