The patch is only for older compilers that I don't regularly test with, it
should not have made a big difference here.

I was going to submit the patch but took a look at some of the remaining
warnings and came across the bug leading to https://lkml.org/lkml/2017/9/15/384,
so I ended up not sending it, but still had it in my queue.

Not sure what happened to that patch though, I think it was in linux-next
at some point (which means I dropped it during rebasing), but it's not
there now.
