Merge tag 'pci-v3.19-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas: "These are fixes for: - a resource management problem that causes a Radeon "Fatal error during GPU init" on machines where the BIOS programmed an invalid Root Port window. This was a regression in v3.16. - an Atheros AR93xx device that doesn't handle PCI bus resets correctly. This was a regression in v3.14. - an out-of-date email address" * tag 'pci-v3.19-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: MAINTAINERS: Update Richard Zhu's email address sparc/PCI: Clip bridge windows to fit in upstream windows powerpc/PCI: Clip bridge windows to fit in upstream windows parisc/PCI: Clip bridge windows to fit in upstream windows mn10300/PCI: Clip bridge windows to fit in upstream windows microblaze/PCI: Clip bridge windows to fit in upstream windows ia64/PCI: Clip bridge windows to fit in upstream windows frv/PCI: Clip bridge windows to fit in upstream windows alpha/PCI: Clip bridge windows to fit in upstream windows x86/PCI: Clip bridge windows to fit in upstream windows PCI: Add pci_claim_bridge_resource() to clip window if necessary PCI: Add pci_bus_clip_resource() to clip to fit upstream window PCI: Pass bridge device, not bus, when updating bridge windows PCI: Mark Atheros AR93xx to avoid bus reset PCI: Add flag for devices where we can't use bus reset
