Ah, sure. Then OK.
Just wondering, who would place this into a uapi header?

I know, but it's set-but-unused field in both of them. So if the defines
went away, this could go too. But given the defines stay, it doesn't
matter. All 3 drivers are old unmaintained crap anyway:
$ git log --oneline --no-merges drivers/tty/synclink*|wc -l
