Re: [PATCH] PCI: pciehp: Add quirk for QDF2400 Command Completed erratum

The QDF2400 controller does not set the Command Completed bit unless writes to the Slot Command register change "Control" bits. Command Completed is never set for writes that only change software notification "Enable" bits. This results in timeouts like this:

pciehp 0000:00:00.0:pcie004: Timeout on hotplug command 0x1038
