That patch should guarantee that we don't loop forever, and if we are going to loop that looks like a reasonable way to handle it.
When I start working on what is the most maintainable way to implement merge my hotplug driver work I will come back and test this.
At the moment it appears that it will at least suffer from detecting a presence change event with a device showing up. Before pci structure for the device is removed. I seem to recall some dead locks on the pciehp work queue hotunplugging a hotplug driver as well.
