--------------------------------

commit c762a2b8 upstream.

As was concluded in a follow-up discussion of commit e0efb316 (tty:
Remove dead termiox code) [1], termiox ioctls never worked, so there is
barely anyone using this interface. We can safely remove the user
definitions for this never adopted interface.
