| Subject: TTY: disable debugging warning |
| |
| From: Jiri Slaby <jslaby@suse.cz> |
| |
| 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. |
