[PATCH v2 2/4] s390/pci: only add specific device in zpci_bus_scan_device()

From: Niklas Schnelle
Date: Mon Mar 06 2023 - 10:10:43 EST


As the name suggests zpci_bus_scan_device() is used to scan a specific
device and thus pci_bus_add_device() for that device is sufficient.
Furthermore move this call inside the rescan/remove locking.
