/* COMMENTS: *****************************************************************
 *
 * Routine Description:
 *
 *    This DPC is called whenever the floppy thread is trying to allocate
 *    the adapter channel (like before doing a read or write).    It saves
 *    the map_register_base in the controller data area, and sets the
 *    AllocateAdapterChannelEvent to awaken the thread.
 *
 * Arguments:
 *
 *    device_object - unused.
 *
 *    irp - unused.
 *
 *    map_register_base - the base of the map registers that can be used
 *    for this transfer.
 *
 *    context - a pointer to our controller data area.
 *
 * Return Value:
 *
 *    Returns Allocation Action 'KeepObject' which means that the adapter
 *    object will be held for now (to be released explicitly later).
