drivers/staging/octeon/octeon-stubs.h:1205:9: warning: cast to pointer from
integer of different size
tree: https://kernel.googlesource.com/pub/scm/linux/kernel/git/davem/net-next.git master
head: 1cb9dfca39eb406960f8f84864ddd6ba329ec321
commit: 171a9bae68c72f2d1260c3825203760856e6793b [57/59] staging/octeon: Allow test build on !MIPS
config: sh-allmodconfig (attached as .config)
compiler: sh4-linux-gcc (GCC) 7.4.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 171a9bae68c72f2d1260c3825203760856e6793b
# save the attached .config to linux build tree
