HI Yinghai,
I think your changes is good, but in this series, we only iterate the pci_host_bridge
in drivers/pci/host-bridge.c. The simple list is enough, of course, if we want to export
this list and support to host bridge hotplug, we must need a new iteration for host bridge,
and your series looks good to me, I read your series history, found Bjorn comment a lot.
So I think Bjorn may have some comments for this.
Thanks!
Yijing.
