char: xillybus: make XILLYBUS_OF depend on HAS_IOMEM
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 XILLYBUS_OF depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ERROR: modpost: "devm_platform_ioremap_resource" [drivers/char/xillybus/xillybus_of.ko] undefined! ------ Reported-by: kernel test robot <[email protected]> Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/ Signed-off-by: Baoquan He <[email protected]> Acked-by: Eli Billauer <[email protected]> Cc: Arnd Bergmann <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
