Btw, this is why I hate compiler warning fix patch series. Even when
they don't actually break the code (and sometimes they do that too),
they can actually end up making the code worse.

The *intent* of that code was to return zero for the CAP_SYS_ADMIN.
But the code has never done that in its lifetime and nobody ever
noticed, so clearly the code shouldn't even have tried.
