Merge branch 'pci/msi'

  - Remove unused pci_irq_get_node() Greg Kroah-Hartman)

  - Move power state check out of pci_msi_supported() (Bjorn Helgaas)

  - Fix incorrect MSI-X masking on resume and revert related nvme quirk for
    Kingston NVME SSD running FW E8FK11.T (Jian-Hong Pan)

  - Make asm/msi.h mandatory and simplify PCI_MSI_IRQ_DOMAIN Kconfig
    (Palmer Dabbelt, Michal Simek)

* pci/msi:
  PCI: Remove PCI_MSI_IRQ_DOMAIN architecture whitelist
  asm-generic: Make msi.h a mandatory include/asm header
  Revert "nvme: Add quirk for Kingston NVME SSD running FW E8FK11.T"
  PCI/MSI: Fix incorrect MSI-X masking on resume
  PCI/MSI: Move power state check out of pci_msi_supported()
  PCI/MSI: Remove unused pci_irq_get_node()
