Seeing as there is shorthand available to use when asking for any type
of interrupt, or any type of message signalled interrupt, leverage it.

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/MSI: Forward MSI-X vector enable error code in
pci_alloc_irq_vectors_affinity()
PCI: Add macro for message signalled interrupt types
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
