You don't have to. Just reorder the patches as suggested by Sam. (First,
make everybody ignore the return value, then change these return types
to void.)

BTW you can mention in this commit log, that this change is possible
after a3123fd0a4a5. That commit made tty_standard_install to always
return 0.
