other fixes: - Add pointers back to device_t objects in softc structures instead of storing the unit and using devclass_get_device(). - Add 'lpbb', 'pcf', 'pps', and 'vpo' child devices to every 'ppbus' device instead of just the first one. - Store softc pointers in si_drv1 of character devices instead of pulling the unit number from the minor number and using devclass_get_softc() and devclass_get_device(). - Store the LP_BYPASS flag in si_drv2 instead of encoding it in the minor number. - Destroy character devices for lpt(4) when detaching the device. - Use bus_print_child_footer() instead of duplicating it in ppbus_print_child() and fix ppbus_print_child()'s return value. - Remove unused AVM ivar from ppbus. - Don't store the 'mode' ivar in the ppbus ivars since we always fetch it from the parent anyway. - Try to detach all the child devices before deleting them in ppbus_detach(). - Use pause() instead of a tsleep() on a dummy address when polling the ppbus. - Use if_printf() and device_printf() instead of explicit names with unit numbers.
