Probably not exactly that, but there seems to be a way with "git cherry". Dunno
how reliable in practice, seems to be based on patch-id so probably can fail
easily if the commit or context changes slightly?

$ git checkout mm-nonmm-stable-2022-12-12
$ git cherry -v origin/master

Seems to have worked in this case and flagged the wifi commit with '-'

HTH,
