The io_addr variable in struct dt3k_private is an ioremap'ed pci resource and should be void __iomem * not a void *.
This quiets a lot of sparse warings for the writew and readw 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/dt3000.c b/drivers/staging/comedi/drivers/dt3000.c index 0d27326..71c3479 100644 --- a/drivers/staging/comedi/drivers/dt3000.c +++ b/drivers/staging/comedi/drivers/dt3000.c @@ -254,7 +254,7 @@ struct dt3k_private { struct pci_dev *pci_dev; resource_size_t phys_addr; - void *io_addr; + void __iomem *io_addr; unsigned int lock; unsigned int ao_readback[2]; unsigned int ai_front; _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
