The primary objective of this patch series is to change the behaviour
of pci_alloc_irq_vectors_affinity such that it forwards the MSI-X enable
error code when appropriate. In the process, though, it was pointed out
that there are multiple places in the kernel which check/ask for message
signalled interrupts (MSI or MSI-X), which spawned the first patch adding
PCI_IRQ_MSI_TYPES. Finally the rest of the chain converts all users to
take advantage of PCI_IRQ_MSI_TYPES or PCI_IRQ_ALL_TYPES, as
appropriate.

Piotr Stankiewicz (15):
  PCI: add shorthand define for message signalled interrupt types
  PCI/MSI: forward MSIx vector enable error code in
    pci_alloc_irq_vectors_affinity
  PCI: use PCI_IRQ_MSI_TYPES where appropriate
  ahci: use PCI_IRQ_MSI_TYPES where appropriate
  crypto: inside-secure - use PCI_IRQ_MSI_TYPES where appropriate
  dmaengine: dw-edma: use PCI_IRQ_MSI_TYPES  where appropriate
  drm/amdgpu: use PCI_IRQ_MSI_TYPES where appropriate
  IB/qib: Use PCI_IRQ_MSI_TYPES where appropriate
  media: ddbridge: use PCI_IRQ_MSI_TYPES where appropriate
  vmw_vmci: use PCI_IRQ_ALL_TYPES where appropriate
  mmc: sdhci: use PCI_IRQ_MSI_TYPES where appropriate
  amd-xgbe: use PCI_IRQ_MSI_TYPES where appropriate
  aquantia: atlantic: use PCI_IRQ_ALL_TYPES where appropriate
  net: hns3: use PCI_IRQ_MSI_TYPES where appropriate
  scsi: use PCI_IRQ_MSI_TYPES and PCI_IRQ_ALL_TYPES where appropriate
