I saw this warning with certain GCC versions for several kernel
cycles, so it's not any recent change that triggers this and it is
not a regression.

GCC is simply wrong here - i have posted a workaround for that but
it is too ugly to be merged upstream.

This patch regresses on older GCC versions and doesnt really address
the GCC false positive warning either, it just removes the inline
function that triggers the warning.
