SubjectRe: [PATCH] gpu: anx7808: fix a missing check of return value
Hi Kangjie,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on linus/master]
[also build test ERROR on v4.20-rc7 next-20181220]
[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/Kangjie-Lu/gpu-anx7808-fix-a-missing-check-of-return-value/20181221-054313
config: nds32-allmodconfig (attached as .config)
compiler: nds32le-linux-gcc (GCC) 6.4.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
