Jiri Slaby b91939f528 TTY: n_tty, simplify read_buf+echo_buf allocation ... ldisc->open and close are called only once and cannot cross. So the tests in open and close are superfluous. Remove them. (But leave sets to NULL to ensure there is not a bug somewhere.) And when the tests are gone, handle properly failures in open. We leaked read_buf if allocation of echo_buf failed before. Now this is not the case anymore.
