Hi Chen,

[auto build test ERROR on regulator/for-next]
[also build test ERROR on v4.3 next-20151106]

url: https://github.com/0day-ci/linux/commits/Chen-Feng/Add-Support-for-Hi6220-PMIC-Hi6553-MFD-Core/20151105-215603
base: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-next
config: arm-allmodconfig (attached as .config)
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
