The acpi_irq_to_vector is called in acpi_os_install_interrupt_handler which is in acpi_init that is before pci_init get called.
So I don't think it is reasonable to use pci_dev in acpi_init.

That's not what willy was proposing.
I understood he was proposing a similar scheme; not to use pci_dev.

Shouldn't this be called acpi_gsi_to_irq(), though?
