Drivers based on the DesignWare core can override the config read accessors by supplying rd_own_conf() and rd_other_conf() function pointers. dw_pcie_rd_conf() calls dw_pcie_rd_own_conf() (for accesses to the root bus) or dw_pcie_rd_other_conf(): dw_pcie_rd_conf dw_pcie_rd_own_conf # if on root bus dw_pcie_rd_other_conf # if not on root bus Previously we checked for rd_other_conf() directly in dw_pcie_rd_conf(), but we checked for rd_own_conf() in dw_pcie_rd_own_conf(). Check for rd_other_conf() in dw_pcie_rd_other_conf() to make this symmetric with the rd_own_conf() checking, and similarly for the write path. No functional change intended.
