From ff450314d5ef05843d3b3bd33fc65f7aaea3b2df Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 21 May 2012 17:52:07 -0700 Subject: [PATCH] staging: comedi: gsc_hpdi: plx9080_iobase and hpdi_iobase are void __iomem * MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The plx9080_iobase and hpdi_iobase variables in struct hpdi_private are ioremap'ed pci resource and should be void __iomem * not void *. This quiets a lot of sparse warings for the writel and readl 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/gsc_hpdi.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/staging/comedi/drivers/gsc_hpdi.c b/drivers/staging/comedi/drivers/gsc_hpdi.c index 79e22b13f734..eeb05553e1a7 100644 --- a/drivers/staging/comedi/drivers/gsc_hpdi.c +++ b/drivers/staging/comedi/drivers/gsc_hpdi.c @@ -296,8 +296,8 @@ struct hpdi_private { resource_size_t plx9080_phys_iobase; resource_size_t hpdi_phys_iobase; /* base addresses (ioremapped) */ - void *plx9080_iobase; - void *hpdi_iobase; + void __iomem *plx9080_iobase; + void __iomem *hpdi_iobase; uint32_t *dio_buffer[NUM_DMA_BUFFERS]; /* dma buffers */ /* physical addresses of dma buffers */ dma_addr_t dio_buffer_phys_addr[NUM_DMA_BUFFERS]; @@ -363,7 +363,7 @@ static void disable_plx_interrupts(struct comedi_device *dev) static void init_plx9080(struct comedi_device *dev) { uint32_t bits; - void *plx_iobase = priv(dev)->plx9080_iobase; + void __iomem *plx_iobase = priv(dev)->plx9080_iobase; /* plx9080 dump */ DEBUG_PRINT(" plx interrupt status 0x%x\n", @@ -672,10 +672,10 @@ static void hpdi_detach(struct comedi_device *dev) if ((priv(dev)) && (priv(dev)->hw_dev)) { if (priv(dev)->plx9080_iobase) { disable_plx_interrupts(dev); - iounmap((void *)priv(dev)->plx9080_iobase); + iounmap(priv(dev)->plx9080_iobase); } if (priv(dev)->hpdi_iobase) - iounmap((void *)priv(dev)->hpdi_iobase); + iounmap(priv(dev)->hpdi_iobase); /* free pci dma buffers */ for (i = 0; i < NUM_DMA_BUFFERS; i++) { if (priv(dev)->dio_buffer[i]) @@ -902,7 +902,7 @@ static void drain_dma_buffers(struct comedi_device *dev, unsigned int channel) uint32_t next_transfer_addr; int j; int num_samples = 0; - void *pci_addr_reg; + void __iomem *pci_addr_reg; if (channel) pci_addr_reg = -- 2.30.2
