PATCH 1/1 ARM: tegra: fix PCIe resource calculation
From: Stephen Warren <[email protected]>
Commit 0acc43c "ARM: tegra: use fixed PCI i/o mapping" re-numbered the resource array entries that the driver used, but missed one location. This causes request_resource() to fail, and the driver to panic.

I'm rebasing the branch and will incorporate it. Thanks for testing.
