    uart is one of our tty drivers and as such it will be part of this.
    (That also means that uart drivers will get cua* and init/lock
    functionality).

    To some extent I'm not entirely sure that lumping anything uart
    finds into one name-category (ttyu*) makes sense, but that is a
    detail decision which can be looked at in the isolated context of
    uart later.

Never attribute to malice what can adequately be explained by incompetence.
