type in assignment (different address spaces)
Hi Arnd,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 041fae9c105ae342a4245cf1e0dc56a23fbb9d3c
commit: 09f6b27d5ddd9ad0ec096d1b0f8decdacc70f0f8 ARM: dove: multiplatform support
date: 9 months ago
config: arm-randconfig-s031-20221215
compiler: arm-linux-gnueabi-gcc (GCC) 12.1.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# apt-get install sparse
