Merge branch 'pci/hotplug'
- fix use-before-set error in ibmphp (Dan Carpenter) - fix pciehp timeouts caused by Command Completed errata (Bjorn Helgaas) - fix refcounting in pnv_php hotplug (Julia Lawall) - clear pciehp Presence Detect and Data Link Layer Status Changed on resume so we don't miss hotplug events (Mika Westerberg) - only request pciehp control if we support it, so platform can use ACPI hotplug otherwise (Mika Westerberg) - convert SHPC to be builtin only (Mika Westerberg) - request SHPC control via _OSC if we support it (Mika Westerberg) - simplify SHPC handoff from firmware (Mika Westerberg) * pci/hotplug: PCI: Improve "partially hidden behind bridge" log message PCI: Improve pci_scan_bridge() and pci_scan_bridge_extend() doc PCI: Move resource distribution for single bridge outside loop PCI: Account for all bridges on bus when distributing bus numbers ACPI / hotplug / PCI: Drop unnecessary parentheses ACPI / hotplug / PCI: Mark stale PCI devices disconnected ACPI / hotplug / PCI: Don't scan bridges managed by native hotplug PCI: hotplug: Add hotplug_is_native() PCI: shpchp: Add shpchp_is_native() PCI: shpchp: Fix AMD POGO identification PCI: shpchp: Use dev_printk() for OSHP-related messages PCI: shpchp: Remove get_hp_hw_control_from_firmware() wrapper PCI: shpchp: Remove acpi_get_hp_hw_control_from_firmware() flags PCI: shpchp: Rely on previous _OSC results PCI: shpchp: Request SHPC control via _OSC when adding host bridge PCI: shpchp: Convert SHPC to be builtin only PCI: pciehp: Make pciehp_is_native() stricter PCI: pciehp: Rename host->native_hotplug to host->native_pcie_hotplug PCI: pciehp: Request control of native hotplug only if supported PCI: pciehp: Clear Presence Detect and Data Link Layer Status Changed on resume PCI: pnv_php: Add missing of_node_put() PCI: pciehp: Add quirk for Command Completed errata PCI: Add Qualcomm vendor ID PCI: ibmphp: Fix use-before-set in get_max_bus_speed() # Conflicts: # drivers/acpi/pci_root.c
