Good.

Hmm, I remember. I suggest you to split the patch into several pieces.
For example moving the code from ->open into ->install can be done
separately. Otherwise it's hard to tell what's wrong with the patch as
a whole.

Also, it would be good to see the patch rebased on the top of my
patch, because tty_port_set/get pieces would be gone from your patch too.
