    USB: don't enable wakeup by default for PCI host controllers · bcca06ef

    This patch (as1199) changes the initial wakeup settings for PCI USB
    host controllers.  The controllers are marked as capable of waking the
    system, but wakeup is not enabled by default.
    
    It turns out that enabling wakeup for USB host controllers has a lot
    of bad consequences.  As the simplest example, if a USB mouse or
    keyboard is unplugged immediately after the computer is put to sleep,
    the unplug will cause the system to wake back up again!  We are better
    off marking them as wakeup-capable and leaving wakeup disabled.
