On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let ALTERA_TSE depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ERROR: modpost: "devm_ioremap" [drivers/net/ethernet/altera/altera_tse.ko] undefined! ------ Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202306211329.ticOJCSv-lkp@intel.com/ Signed-off-by: Baoquan He <bhe@redhat.com> Cc: Joyce Ooi <joyce.ooi@intel.com> Cc: "David S.
