From ae83707f39e1b8f2a15af3868bba25ce4fa93364 Mon Sep 17 00:00:00 2001 From: Niklas Schnelle Date: Mon, 6 Mar 2023 16:10:12 +0100 Subject: [PATCH] s390/pci: only add specific device in zpci_bus_scan_device() 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.
