Subject: PCI: designware: Make dw_pcie_rd_own_conf(), etc., static
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73e408508bf6c76d8dc06f044f0e4703a1e27f14;p=linux-beck.git

PCI: designware: Make dw_pcie_rd_own_conf(), etc., static

The following variables and functions are used only in pcie-designware.c,
so make them static:

  global_io_offset
  dw_pcie_rd_own_conf()
  dw_pcie_wr_own_conf()
  dw_pcie_setup()
  dw_pcie_scan_bus()
  dw_pcie_map_irq()
