+Subject: [PATCH v2] MIPS: PCI: scan PCI controllers in reverse order
+
+Commit 23dac14d058f ("MIPS: PCI: Use struct list_head lists") changed
+the controller list from reverse to straight order without taking care
+of the changed order for the scan of the recorded PCI controllers.
+
+Traverse the list in reverse order to restore the former behaviour.
+
+This patches fixes the following PCI error on lantiq:
+
+  pci 0000:01:00.0: BAR 0: error updating (0x1c000004 != 0x000000)
+
+Fixes: 23dac14d058f ("MIPS: PCI: Use struct list_head lists")
