I mean, it's in an error handling pathway that could be hit if there's
an -ENOMEM error on an IRQ-action allocation. So it's probably
mostly a theoretical issue but I wouldn't go as far as to claim it could
never happen either as there does appear to be a plausible way to
hit it.

Do theoretical but still potentially reachable bug fixes go in net or net-next
generally when they haven't been reproduced on real hardware without
an artificial test harness?

I had assumed that since the commit message made it clear that this was
a bug fix and not a new feature then that would be sufficient info to know
which branch it would go in, but I guess it's not quite that simple?
