Ah! I was in 4.19 when I saw the problem. I then confirmed that the
code in mainline was the same and that the new version built fine with
my patch, but I didn't go back and confirm the problem there.

OK, I just checked linux/master and can confirm there's no problem
there. Sorry for the noise then...

I wonder if perhaps we should revert commit caf6fe91ddf6 ("modsign:
Abort modules_install when signing fails") then to be consistent?

It's probably not worth it. In general I prefer linux-stable to be as
just cherry-picks of mainline as much as possible. When it starts
forking then future picks get harder. Sure in this case it's unlikely
that someone will get tripped up by an "&&" vs a ";" when picking
future changes, but given that it's not super urgent I guess I'd vote
that we skip it.
