SubjectRe: [PATCH v2 1/9] staging: ccree: introduce CryptoCell HW driver
Hi Gilad,

[auto build test ERROR on linus/master]
[also build test ERROR on v4.11-rc7]
[cannot apply to staging/staging-testing next-20170420]
[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/Gilad-Ben-Yossef/staging-ccree-add-Arm-TrustZone-CryptoCell-REE-driver/20170420-222023
config: i386-allmodconfig (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
# save the attached .config to linux build tree
make ARCH=i386
