commit: 788c2ef8c423ccd8c62a471c7e7debe115b3e124 [9951/9999] drm amdgpu: SI UVD add uvd_v3_1 to makefile
config: s390-randconfig-s032-20200624 (attached as .config)
compiler: s390-linux-gcc (GCC) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-dirty
git checkout 788c2ef8c423ccd8c62a471c7e7debe115b3e124
# save the attached .config to linux build tree
make W=1 C=1 ARCH=s390 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag as appropriate
