SubjectRe: [patch net-next 08/11] net: hns: register phy device in each mac initial sequence
Hi,

[auto build test ERROR on net-next/master]

url: https://github.com/0day-ci/linux/commits/Yisen-Zhuang/net-hns-add-support-of-ACPI/20160513-161402
config: ia64-allyesconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 4.9.0
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
make.cross ARCH=ia64

Note: the linux-review/Yisen-Zhuang/net-hns-add-support-of-ACPI/20160513-161402 HEAD b35bbec71070d6f7073f4bce154081fac5f156ec builds fine.
It only hurts bisectibility.
