    (PNP: increase the maximum number of resources)
    increased PNP_MAX_PORT to 24 from 8.
    It also added a test and a complaint when a
    machine exceeded the limit, causing:
    
    pnpacpi: exceeded the max number of IO resources: 24

    We should have been squawking about this all along,
    as this is a potentially serious issue.
    
    For now, simply burn some dynamic bytes and
    increase the limit by another 16 to 40.
    There is no guarantee that this will satisfy
    every system on Earth.  It probably will not,
    but it should be an improvement.
    
    In the future, PNPACPI should allocate resource
    structures as needed, rather than max-sized arrays.
