That commit actually split the loop to two loops, so second loop still

|    PCI: hotplug: pciehp: Removed check for hotplug of display devices

|    Removed check to prevent hotplug of display devices within pciehp.
|    Originally this was thought to have been required within the PCI

only removed the first one in pciehp_configure_device().

So you can drop that checking.

Thanks
