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 depend PCMCIA on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset. ------------------------------------------------------- ld: drivers/pcmcia/cistpl.o: in function `set_cis_map': cistpl.c:(.text+0x1202): undefined reference to `ioremap' ld: cistpl.c:(.text+0x13b0): undefined reference to `iounmap' ld: cistpl.c:(.text+0x14a6): undefined reference to `iounmap' ld: cistpl.c:(.text+0x1544): undefined reference to `ioremap' ld: drivers/pcmcia/cistpl.o: in function `release_cis_mem': cistpl.c:(.text+0x3f14): undefined reference to `iounmap' Link: https://lore.kernel.org/all/Y0TcaZD4nB1w+mAQ@MiWiFi-R3L-srv/T/#u Signed-off-by: Baoquan He Cc: Dominik Brodowski Cc: Arnd Bergmann Cc: Jonathan Cameron Cc: Linus Walleij Cc: Thomas Bogendoerfer Reviewed-by: Niklas Schnelle Acked-by: Arnd Bergmann --- drivers/pcmcia/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/pcmcia/Kconfig b/drivers/pcmcia/Kconfig index 1525023e49b6..7c412bbe8bbe 100644 --- a/drivers/pcmcia/Kconfig +++ b/drivers/pcmcia/Kconfig @@ -20,6 +20,7 @@ if PCCARD config PCMCIA tristate "16-bit PCMCIA support" + depends on HAS_IOMEM select CRC32 default y help
