From 3882e5c7152cc518ad5e9362a72f30f244394046 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 13 May 2020 17:38:58 -0500 Subject: [PATCH] PCI: Fix pci_register_host_bridge() device_register() error handling [ Upstream commit 1b54ae8327a4d630111c8d88ba7906483ec6010b ] If device_register() has an error, we should bail out of pci_register_host_bridge() rather than continuing on.
