> We can't just save the most recent cflag setting in the driver?

As I've said, the problem is that we don't know what the correct cflag
setting is - the tty layer is the only thing which authoritively knows
and the creaky tty layer is not setup for power management.

The additional issue is that the only driver which knows how to do this
is serial_core, and that can't save it in a static location because
there may be multiple serial ports (of differing types) configured as
console.

All round, I don't see an easy solution to this.  (If there were I'd
have already fixed it - I've known about this issue since I wrote the
PM serial support.)
