Hi Brad,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on v4.16-rc4]
[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/Brad-Mouring/net-macb-Reorganize-macb_mii-bringup/20180313-113743
config: x86_64-randconfig-x003-201810 (attached as .config)
compiler: gcc-7 (Debian 7.3.0-1) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64
Note: the linux-review/Brad-Mouring/net-macb-Reorganize-macb_mii-bringup/20180313-113743 HEAD dbe45eb4d14a7cd3d0b9c7ee8e7ca034c1ef3852 builds fine.
It only hurts bisectibility.
