SubjectRe: [PATCH] crypto: s5p-sss: Add HASH support for Exynos
Hi Kamil,

[auto build test WARNING on cryptodev/master]
[also build test WARNING on v4.13 next-20170915]
[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/Kamil-Konieczny/crypto-s5p-sss-Add-HASH-support-for-Exynos/20170915-161309
base: https://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git master
config: tile-allmodconfig (attached as .config)
compiler: tilegx-linux-gcc (GCC) 4.6.2
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
make.cross ARCH=tile
