From ce6a727276c55c486fe65e1f41ed8afcdacec75d Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 18 Apr 2020 10:16:37 +0200 Subject: [PATCH] PCI: v3-semi: Fix a memory leak in v3_pci_probe() error handling paths [ Upstream commit bca718988b9008d0d5f504e2d318178fc84958c1 ] If we fails somewhere in 'v3_pci_probe()', we need to free 'host'. Use the managed version of 'pci_alloc_host_bridge()' to do that easily. The use of managed resources is already widely used in this driver.
