Subject: [patch 09/20] acpi bridge hotadd: Remove hot-plugged devices that could not be allocated resources

From: Rajesh Shah <rajesh.shah@intel.com>
When hot-plugging an I/O hierarchy that contains many bridges and leaf
devices, it's possible that there are not enough resources to start all the
device present. If we fail to assign a resource, clear the corresponding
value in the pci_dev structure, so other code can take corrective action.
