sparse: incorrect type in assignment (different address spaces)
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 26e122e97a3d0390ebec389347f64f3730fdf48f
commit: 670d0a4b10704667765f7d18f7592993d02783aa sparse: use identifiers to define address spaces
date: 6 days ago
config: alpha-randconfig-s031-20200624 (attached as .config)
compiler: alpha-linux-gcc (GCC) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-dirty
git checkout 670d0a4b10704667765f7d18f7592993d02783aa
# save the attached .config to linux build tree
make W=1 C=1 ARCH=alpha CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
