I have sparse 0.6.3 on an Debian bullseye amd64 system. Sources are from
linux-next next-20210723
make allnoconfig
cat >> .config << "EOF"
CONFIG_NET=y
CONFIG_INET=y
CONFIG_BATMAN_ADV=y
CONFIG_BATMAN_ADV_DAT=y
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,
Sven
