    PCI: Use positive flags in pci_alloc_irq_vectors() · 4fe0d154
    Christoph Hellwig authored
    Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of
    certain interrupt types, pass positive flags like PCI_IRQ_LEGACY,
    PCI_IRQ_MSI, etc., to specify the acceptable interrupt types.
    This is based on a number of pending driver conversions that just happend
    to be a whole more obvious to read this way, and given that we have no
    users in the tree yet it can still easily be done.
    I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting
    all interrupt types very simple.
