drivers/char/tty_io.c schedules flush_to_ldisc work. This work can potentially reschedule itself, making call to flush_scheduled_work() at the end of release_dev() useless :-(
Unfortunately I have no idea what is that code trying to do - we already did tty->ldisc.close() and replaced tty->ldisc with something else when we call flush_scheduled_work(), so I doubt that work we are waiting for can do anything useful even if TTY_DONT_FLIP is not set...
