Subject: [PATCH 3/8] PCI: Assign CardBus bus number only during the second pass.
Date: Thu, 23 Jan 2014 21:59:23 +0100 [thread overview]
Message-ID: <1390510768-5652-4-git-send-email-andreas.noever@gmail.com> (raw)
In-Reply-To: <1390510768-5652-1-git-send-email-andreas.noever@gmail.com>
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.
