Jiri Slaby fa7501e57e tty: remove tty_operations::chars_in_buffer for non-buffering ... The only user of tty_ops::chars_in_buffer is tty_chars_in_buffer. And it considers tty_ops::chars_in_buffer optional. In case it's NULL, zero is returned. So remove all those chars_in_buffer from tty_ops which return zero. (Zero means such driver doesn't buffer.)
