Subject: PCI: layerscape: Refactor ls1021_pcie_host_init()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fa92dba92c0026a8378085dbeab8a1d8ad8476c6;p=linux.git

PCI: layerscape: Refactor ls1021_pcie_host_init()

ls1021_pcie_host_init() duplicated the code in the generic
ls_pcie_host_init().  Call ls_pcie_host_init() instead of duplicating the
code.
