[Qemu-devel] [PATCH V5 1/7] hw/pcie-root-port: Fix PCIe root port initialization

[Marcel Apfelbaum <marcel@redhat.com>]

Specify the root port interrupt pin as part of the init
process for cases when msi/msix are not enabled.

Fixes "hw/pci/pci.c:196:23: runtime error: shift exponent -1 is negative"
warning from clang's sanitizer.
