- use tty, not hp->tty wherever possible
- pass tty down to some functions and go to step one
- do not defer tty_hangup calls -- it is as simple as schedule_work,
so might be called with hp->lock held
- do not defer tty buffer flips -- since the driver does not use
low_latency (it cannot actually), the flip is a simple tail move
plus schedule_work. It will make our life easier in the next patch.
