If anyone has any objections, please let me know. ------------------ From: Jiri Slaby commit 34dcfb8479ab3c3669561eb9279284cb0eda2572 upstream. We added a warning to flush_to_ldisc to report cases when it is called with a NULL tty. It was for debugging purposes and it lead to a patchset from Peter Hurley. The patchset however did not make it to 3.9, so disable the warning now to not disturb people. We can re-add it when the series is in and we are hunting for another bugs.
