I have a diff that mirrors the GCC infrastructure, which should work for this, feel free to copy it: https://lore.kernel.org/r/20210310225240.4epj2mdmzt4vurr3@archlinux-ax161/ If you want to shut up the warning for all supported versions of clang, switch 130000 for 110000 and __diag_clang_11() for __diag_clang_13().
