I have sparse 0.6.3 on an Debian bullseye amd64 system. Sources are from
linux-next next-20210723

make allnoconfig
cat >> .config << "EOF"
make olddefconfig
make CHECK="sparse -Wbitwise-pointer" C=1

I should maybe have made this clearer in the last sentence of the first
paragraph: "This is also true for pointers to variables with this type when
-Wbitwise-pointer is activated."

Kind regards,
