Subject: [PATCH] PCI: Fix pci_register_host_bridge() device_register() error handling
Git-commit: 1b54ae8327a4d630111c8d88ba7906483ec6010b
Patch-mainline: v5.8-rc1
References: bsc#1051510
If device_register() has an error, we should bail out of
pci_register_host_bridge() rather than continuing on.
Fixes: 37d6a0a6f470 ("PCI: Add pci_register_host_bridge() interface")
