'oct_mdio_readq'
Hi Nathan,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: dcb7fd82c75ee2d6e6f9d8cc71c52519ed52e258
commit: b8fb640643fcdb3bca84137c4cec0c649b25e056 net: mdio-octeon: Fix Kconfig warnings and build errors
date: 11 months ago
config: m68k-randconfig-r015-20200706 (attached as .config)
compiler: m68k-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout b8fb640643fcdb3bca84137c4cec0c649b25e056
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=m68k
If you fix the issue, kindly add following tag as appropriate
