I am not sure I understand -- my reading of Kees' message is that he
would prefer to get the warning (rather than the kernel) fixed before
GCC 13 releases.

Are you asking to have the option disabled until GCC 13 releases and
reevaluate then? How many warnings are you getting? Are those actual
errors or `-Werror`?

Cheers,
