commit: e49c5c3ebe679dfc69b9e854dd717ee8ed64d4c9 [90/562] drm/amd/dal: Simplify
return value for HW programming

compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430
reproduce:
git checkout e49c5c3ebe679dfc69b9e854dd717ee8ed64d4c9
# save the attached .config to linux build tree
make ARCH=i386
Note: it may well be a FALSE warning. FWIW you are at least aware of it now.
Note: the radeon-alex/drm-next-4.8-wip-dal HEAD
febc9e1f8b905e5df7b34fb697ffc4968a940577 builds fine.
