That's exactly what I was mulling over in my head today (I'm the author of this blog post). If there's some way to simply provide a v3 of this patch while leaving the credit with the original author, I'd love to do it. I just didn't want to step on anybody's toes, and I don't know the etiquette. I think this kind of thing happens more often than we realize. I've seen similar situations before on other drivers.
Download the raw patch from lore.kernel.org, apply it with "git am", fix up the commit message with "git commit --amend", add your "Signed-off-by" below the existing one, submit with "git-send-email" or "git format-patch" + "msmtp".
That way the commit author remains the same because "git format-patch" includes a "From:" line in the message body which "git am" will interpret as the commit author when the maintainer applies the patch.
Honestly, fuck the ettiquite. Reubsmit the patch with fixedup styling and attribution to the original author. If it ruffles some feathers ? Who cares. Hopefully it shakes things up.
