Subject: [PATCH] PCI: v3-semi: Fix a memory leak in v3_pci_probe() error handling paths
Git-commit: bca718988b9008d0d5f504e2d318178fc84958c1
Patch-mainline: v5.8-rc1
References: git-fixes
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.
