* Last minute TTY API change: remove mutex argument from tty_alloc().ed2009-05-291-1/+1
| | | | | | | | | | I don't want people to override the mutex when allocating a TTY. It has to be there, to keep drivers like syscons happy. So I'm creating a tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex() should eventually be removed. The advantage of this approach, is that we can just remove a function, without breaking the regular API in the future.

* Remove unused consdev structure fields.ed2008-10-271-2/+1
| | | | | | The cn_unit and cn_tp fields don't seem to be used anywhere. Some drivers set them, while others don't. Just remove them, in an attempt to make our consdev code a little easier to understand.
