I'm not a gmail heavy user, but I remember it has an `app password`?
Also you could use other email clients like mutt or thunderbird in plain
text (as long as such email clients don't break the patch.)

If none of these work, you could also submit a pull request with your
signed-off-by and I will cherry-pick this, yet I think most
linux-kernel related projects don't directly use github honestly.

Thanks,
Gao Xiang
