[#name], and not [name]. So, change them.

    It would be desirable if applications could depend on drivers
    supporting all I/O interfaces, but as much as the complex memory
    mapping I/O can be inadequate for some devices we have no reason to
    require this interface, which is most useful for simple applications

    At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
    the same, and :ref:`select() <func-select>` is too important to be optional.
