[PATCH 5/5] Staging: ipack/bridges/tpci200: fix kernel oops when uninstalling a device

[Samuel Iglesias Gonsalvez]

When uninstalling a device, the call to the ipack_bus_ops remove() frees
resources in the ipack device driver but without unregistering the device.

It generates a kernel oops when somebody wants to unregister the device.
