The las0, las1, and lcfg variables in struct rtdPrivate are all ioremap'ed pci resources and should be void __iomem * not void *. This quiets a lot of sparse warings for the writel and readl like: warning: incorrect type in argument 1 (different address spaces) expected void const volatile [noderef] <asn:2>*addr got void *<noident> warning: incorrect type in argument 2 (different address spaces) expected void volatile [noderef] <asn:2>*addr got void * Signed-off-by: H Hartley Sweeten <hsweeten@xxxxxxxxxxxxxxxxxxx> Cc: Ian Abbott <abbotti@xxxxxxxxx> Cc: Mori Hess <fmhess@xxxxxxxxxxxxxxxxxxxxx> Cc: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- diff --git a/drivers/staging/comedi/drivers/rtd520.c b/drivers/staging/comedi/drivers/rtd520.c index 0c15b82..0e62bae 100644 --- a/drivers/staging/comedi/drivers/rtd520.c +++ b/drivers/staging/comedi/drivers/rtd520.c @@ -339,9 +339,9 @@ static const struct rtdBoard rtd520Boards[] = { */ struct rtdPrivate { /* memory mapped board structures */ - void *las0; - void *las1; - void *lcfg; + void __iomem *las0; + void __iomem *las1; + void __iomem *lcfg; unsigned long intCount; /* interrupt count */ long aiCount; /* total transfer size (samples) */ _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
