Linus turned that warning off in 2020: commit 78a5255ffb6a1af189a83e493d916ba1c54d8c75 Author: Linus Torvalds <[email protected]> Date: Sat May 9 13:57:10 2020 -0700 Stop the ad-hoc games with -Wno-maybe-initialized You need to enable it by hand to see the warning: make KBUILD_CFLAGS_KERNEL=-Wmaybe-uninitialized CFLAGS_MODULE=-Wmaybe-uninitialized W=2 enables it too but it also enables lots of other crap so it's useless.
