Alex Chiang 5d4a4b25dd PCI Hotplug: acpiphp: grab refcount on p2p subordinate bus ... If a logical hot unplug (remove) is performed on a bridge claimed by acpiphp and then acpiphp is unloaded, we will encounter an oops. This is because acpiphp will access the bridge's subordinate bus, which was released by the user's prior hot unplug. The solution is to grab a reference on the subordinate PCI bus. This will prevent the bus from release until acpiphp is unloaded.
