Staging: ipack/bridges/tpci200: fix kernel oops when uninstalling a device
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. Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
