Subject: PCI/ASPM: Deallocate upstream link state even if device is not PCIe
X-Git-Tag: v3.9-rc1~82^2~5^2~1

PCI/ASPM: Deallocate upstream link state even if device is not PCIe

On PCI bus hotplug removal, pcie_aspm_exit_link_state() can potentially
skip parent devices that have link_state allocated.  Instead of exiting
early if a given device is not PCIe, check whether or not the device's
parent has link_state allocated.  This enables pcie_aspm_exit_link_state()
to properly clean up parent link_state when the last function in a slot
might not be PCIe.
