However, vme_bus_remove() is called when a VME device is removed from the bus and not when the bus is removed; as it calls the VME device driver's cleanup function. Without this function, the remove() in the VME device driver is never called and VME device drivers cannot be reloaded again. Here we restore the remove function that was deleted in that commit, and the reference to the function in the bus structure.
