From ef07991a95de76b07594448c3521361831ec2cfe Mon Sep 17 00:00:00 2001
From: Hauke Mehrtens <hauke@hauke-m.de>

Subject: [PATCH 2/2] PCI: iproc: Free resource list after registration
The resource list is only used in the setup process and was never freed.
pci_add_resource() allocates a memory area to store the list item.
Fix the memory leak.
