From 4aa7419e082ef5ca38f8934d38fda5909a27962b Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 21 May 2012 18:10:07 -0700 Subject: [PATCH] staging: comedi: ii_pci20kc: iobase and ioaddr are void __iomem * MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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] *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 Cc: Greg Kroah-Hartman Signed-off-by: Greg Kroah-Hartman --- drivers/staging/comedi/drivers/ii_pci20kc.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/staging/comedi/drivers/ii_pci20kc.c b/drivers/staging/comedi/drivers/ii_pci20kc.c index f0a579a04a7d..6f6947602398 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 */
