Merge tag 'pci-v3.17-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas: "These fix: - Boot video device detection on dual-GPU Apple systems - Hotplug fiascos on VGA switcheroo with radeon & nouveau drivers - Boot hang on Freescale i.MX6 systems - Excessive "no hotplug settings from platform" warnings In particular: Enumeration - Don't default exclusively to first video device (Bruno Prémont) PCI device hotplug - Remove "no hotplug settings from platform" warning (Bjorn Helgaas) - Add pci_ignore_hotplug() for VGA switcheroo (Bjorn Helgaas) Freescale i.MX6 - Put LTSSM in "Detect" state before disabling (Lucas Stach)" * tag 'pci-v3.17-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: vgaarb: Drop obsolete #ifndef vgaarb: Don't default exclusively to first video device with mem+io ACPIPHP / radeon / nouveau: Remove acpi_bus_no_hotplug() PCI: Remove "no hotplug settings from platform" warning PCI: Add pci_ignore_hotplug() to ignore hotplug events for a device PCI: imx6: Put LTSSM in "Detect" state before disabling it MAINTAINERS: Add Lucas Stach as co-maintainer for i.MX6 PCI driver
