commit: fdc916c8be24375d63c36ae363f71e59becfb8f2 [262/270] drm/amdgpu: Add
sysfs file for PCIe usage v4
config: i386-randconfig-s3-201901 (attached as .config)
compiler: gcc-6 (Debian 6.4.0-9) 6.4.0 20171026
reproduce:
git checkout fdc916c8be24375d63c36ae363f71e59becfb8f2
# save the attached .config to linux build tree
make ARCH=i386
Note: the radeon-alex/amd-staging-drm-next HEAD
d2d07f246b126b23d02af0603b83866a3c3e2483 builds fine.
It only hurts bisectibility.
