The iobase variables in struct pci20xxx_subdev_private and ioaddr variable in struct pci20xxx_private should be void __iomem * not void *.
This quiets a lot of sparse warings for the writeb and readb calls 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 <[email protected]> Cc: Ian Abbott <[email protected]> Cc: Mori Hess <[email protected]> Cc: Greg Kroah-Hartman <[email protected]> --- diff --git a/drivers/staging/comedi/drivers/ii_pci20kc.c b/drivers/staging/comedi/drivers/ii_pci20kc.c index f0a579a..6f69476 100644 --- a/drivers/staging/comedi/drivers/ii_pci20kc.c +++ b/drivers/staging/comedi/drivers/ii_pci20kc.c @@ -135,15 +135,15 @@ options for PCI-20341M: #define PCI20341_SCANLIST 0x80 /* Channel/Gain Scan List */ union pci20xxx_subdev_private { - void *iobase; + void __iomem *iobase; struct { - void *iobase; + void __iomem *iobase; const struct comedi_lrange *ao_range_list[2]; /* range of channels of ao module */ unsigned int last_data[2]; } pci20006; struct { - void *iobase; + void __iomem *iobase; int timebase; int settling_time; int ai_gain; @@ -152,7 +152,7 @@ union pci20xxx_subdev_private { struct pci20xxx_private { - void *ioaddr; + void __iomem *ioaddr; union pci20xxx_subdev_private subdev_private[PCI20000_MODULES]; }; @@ -210,7 +210,7 @@ static int pci20xxx_attach(struct comedi_device *dev, if (ret < 0) return ret; - devpriv->ioaddr = (void *)(unsigned long)it->options[0]; + devpriv->ioaddr = (void __iomem *)(unsigned long)it->options[0]; dev->board_name = "pci20kc"; /* Check PCI-20001 C-2A Carrier Board ID */ _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
