(CCing Michael and Marcel)
For better visibility I suggest copying the maintainers of hw/pci/pci.c when
submitting this patch in the next version:
$ ./scripts/get_maintainer.pl -f hw/pci/pci.c
"Michael S. Tsirkin" <mst@redhat.com> (supporter:PCI)
Marcel Apfelbaum <marcel.apfelbaum@gmail.com> (supporter:PCI)
qemu-devel@nongnu.org (open list:All patches CC here)
We can push this via the RISC-V tree but we need an ack/review from the PCI
overlords.
Thanks,
Daniel
