From f01fc4177352614743ce3fe289687387fcf9e6c6 Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Mon, 10 Jul 2017 13:34:08 +0100 Subject: [PATCH] ARM/PCI: Fix pcibios_init_resource() struct pci_host_bridge leak Since commit 97ad2bdcbe85 ("ARM/PCI: Convert PCI scan API to pci_scan_root_bus_bridge()") the space for struct pci_sys_data is allocated by pci_alloc_host_bridge() as part of the struct pci_host_bridge. Therefore, failure paths must deallocate the entire pci_host_bridge by using pci_free_host_bridge().
