+Subject: [PATCH 115/115] PCI: layerscape: call dw_pcie_setup_rc() in host
+ initialization
+
+A previous patch moved some Root Complex programming from
+dw_pcie_host_init() to dw_pcie_setup_rc() where it belongs,
+while the pci-layerscape driver didn't call dw_pcie_setup_rc()
+anywhere after that. This patch is to add dw_pcie_setup_rc()
+calling in layerscape host initialization to fix ls1012a pci
+issue caused by that patch.
+
+Fixes: c49b76f3c613("PCI: designware: Move Root Complex setup
+       code to dw_pcie_setup_rc()")
