Shachar Shemesh aa3c8af863 tty ldisc: Close/Reopen race prevention should check the proper flag ...

Commit acfa747b introduced the TTY_HUPPING flag to distinguish
closed TTY from currently closing ones. The test in tty_set_ldisc
still remained pointing at the old flag. This causes pppd to
sometimes lapse into uninterruptible sleep when killed and
restarted.
