It was, umm, naive to assume that was the only outstanding patch against
mxser.c. I had four patches. One wasn't actually in use and one I just
dropped, so we now have
serial-fix-up-offenders-peering-at-baud-bits-directly.patch and
const-struct-tty_operations.patch.

That wasn't a good way to do this. It would have been (much) better to
have one patch which copies mxser.c to mxser_new.c and *nothing else*.
Then, new patches which update mxser_new.c.

So I have converted your patch into one which simply copies mxser.[ch] to
mxser_new.[ch] and which makes no other changes. The versions which were
copied were those _after_ the two pending patches were applied. Please
send updates against those new files, thanks.
