From 86a5eb8ccef09916e622b43f97f115c2526d7d2e Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 21 May 2012 17:55:33 -0700 Subject: [PATCH] staging: comedi: icp_multi: io_addr is a void __iomem * MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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] *addr    got void * warning: incorrect type in argument 2 (different address spaces)    expected void volatile [noderef] *addr    got void * Signed-off-by: H Hartley Sweeten Cc: Ian Abbott Cc: Mori Hess Signed-off-by: Greg Kroah-Hartman --- drivers/staging/comedi/drivers/icp_multi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/comedi/drivers/icp_multi.c b/drivers/staging/comedi/drivers/icp_multi.c index fdc596f..f870d3d 100644 --- a/drivers/staging/comedi/drivers/icp_multi.c +++ b/drivers/staging/comedi/drivers/icp_multi.c @@ -148,7 +148,7 @@ struct boardtype { struct icp_multi_private { struct pcilst_struct *card; /* pointer to card */ char valid; /* card is usable */ - void *io_addr; /* Pointer to mapped io address */ + void __iomem *io_addr; /* Pointer to mapped io address */ resource_size_t phys_iobase; /* Physical io address */ unsigned int AdcCmdStatus; /* ADC Command/Status register */ unsigned int DacCmdStatus; /* DAC Command/Status register */ -- 2.7.4
