[PATCH v1 0/2] PCI: hotplug: Add checks to avoid doing hotplug on PCIe Upstream Ports

Hi All,

PCIe Upstream Ports are not hotplug-capable by definition, but it turns out
that in some cases, if the system is configured in a particularly interesting
way, the kernel may be made attempt to operate an Upstream Port as a hotplug
one which causes functional issues to appear.

The following 2 patches amend the code to prevent this behavior from occurring.

Thanks!
