Some drivers call the tty_schedule_flip() function instead of tty_flip_buffer_push(). In that case the work queue is always used, regardless the tty->low_latency flag. That's why tried to get rid of the tty_schedule_flip() function. But from the first review remarks on the "tty: cleanup duplicate functions in tty_buffer" patch, that patch seems to be invalid. So in that case this patch is invalid also.
