From 619c8c310f7f21e59a7e2b53795183c34401a599 Mon Sep 17 00:00:00 2001 From: Andreas Noever Date: Thu, 23 Jan 2014 21:59:23 +0100 Subject: [PATCH] PCI: Assign CardBus bus number only during the second pass 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.
