SubjectRe: [PATCH 2/2] net: ethernet: nixge: Add support for National Instruments XGE netdev
Hi Moritz,

[auto build test ERROR on net-next/master]
[also build test ERROR on v4.12 next-20170714]
[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/Moritz-Fischer/dt-bindings-net-Add-bindings-for-National-Instruments-XGE-netdev/20170714-125718
config: um-allyesconfig (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=um
