Hi Damien.Horsley,
[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]
config: blackfin-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
git checkout 5037c15dd47c86ab337b73c7f9ffcabe1bb86f3b
# save the attached .config to linux build tree
make.cross ARCH=blackfin
Note: it may well be a FALSE warning. FWIW you are at least aware of it now.
