Subject: [PATCH 09/12] PCI: make no_pci_devices() use the pci_bus_type list
Date: Thu, 14 Feb 2008 16:40:07 -0800	[thread overview]
Message-ID: <1203036010-27988-9-git-send-email-gregkh@suse.de> (raw)
In-Reply-To: <20080215003909.GA27981@kroah.com>

no_pci_devices() should use the driver core list of PCI devices, not our
"separate" one.
