From 18c4342aa56d70176eea85021e6fe8f6f8f39c7b Mon Sep 17 00:00:00 2001
From: Hauke Mehrtens <hauke@hauke-m.de>
Date: Sun, 24 May 2015 22:37:02 +0200
Subject: [PATCH 1/2] PCI: iproc: Directly add PCI resources
The struct iproc_pcie.resources member was pointing to a stack variable and
is invalid after the registration function returned.
Remove this pointer and add a parameter to the function.
