   4 Subject: [PATCH 115/115] PCI: layerscape: call dw_pcie_setup_rc() in host
   5  initialization
   6
   7 A previous patch moved some Root Complex programming from
   8 dw_pcie_host_init() to dw_pcie_setup_rc() where it belongs,
   9 while the pci-layerscape driver didn't call dw_pcie_setup_rc()
  10 anywhere after that. This patch is to add dw_pcie_setup_rc()
  11 calling in layerscape host initialization to fix ls1012a pci
  12 issue caused by that patch.
  13
  14 Fixes: c49b76f3c613("PCI: designware: Move Root Complex setup
  15        code to dw_pcie_setup_rc()")
