[PATCH 3/8] PCI: Assign CardBus bus number only during the second pass.

From: Andreas Noever
Date: Thu Jan 23 2014 - 16:02:01 EST


Right now the CardBus code in pci_scan_bridge is executed during both
passes. Since we always allocate the bus number ourselves it makes sense
to put it into the second pass.
