Merge branch 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6
* 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: (75 commits) PCI hotplug: clean up acpi_run_hpp() PCI hotplug: acpiphp: use generic pci_configure_slot() PCI hotplug: shpchp: use generic pci_configure_slot() PCI hotplug: pciehp: use generic pci_configure_slot() PCI hotplug: add pci_configure_slot() PCI hotplug: clean up acpi_get_hp_params_from_firmware() interface PCI hotplug: acpiphp: don't cache hotplug_params in acpiphp_bridge PCI hotplug: acpiphp: remove superfluous _HPP/_HPX evaluation PCI: Clear saved_state after the state has been restored PCI PM: Return error codes from pci_pm_resume() PCI: use dev_printk in quirk messages PCI / PCIe portdrv: Fix pcie_portdrv_slot_reset() PCI Hotplug: convert acpi_pci_detect_ejectable() to take an acpi_handle PCI Hotplug: acpiphp: find bridges the easy way PCI: pcie portdrv: remove unused variable PCI / ACPI PM: Propagate wake-up enable for devices w/o ACPI support ACPI PM: Replace wakeup.prepared with reference counter PCI PM: Introduce device flag wakeup_prepared PCI / ACPI PM: Rework some debug messages PCI PM: Simplify PCI wake-up code ... Fixed up conflict in arch/powerpc/kernel/pci_64.c due to OF device tree scanning having been moved and merged for the 32- and 64-bit cases. The 'needs_freset' initialization added in 6e19314cc ("PCI/powerpc: support PCIe fundamental reset") is now in arch/powerpc/kernel/pci_of_scan.c.

8 * pci_find_device - begin or continue searching for a PCI device by vendor/device id
9 * @vendor: PCI vendor id to match, or %PCI_ANY_ID to match all vendor ids
10 * @device: PCI device id to match, or %PCI_ANY_ID to match all device ids
11 * @from: Previous PCI device found in search, or %NULL for new search.
12 *
13 * Iterates through the list of known PCI devices. If a PCI device is found
14 * with a matching @vendor and @device, a pointer to its device structure is
15 * returned. Otherwise, %NULL is returned.
16 * A new search is initiated by passing %NULL as the @from argument.
17 * Otherwise if @from is not %NULL, searches continue from next device
18 * on the global list.
19 *
20 * NOTE: Do not use this function any more; use pci_get_device() instead, as
21 * the PCI device returned by this function can disappear at any moment in
22 * time.
