For more details see [1] and [2]. This patch will remove the following sparse warning (i.e. when copiling with "make C=1"): * warning: incorrect type in assignment (different address spaces) References: [1] A new I/O memory access mechanism (Sep 15, 2004) http://lwn.net/Articles/102232/ [2] Being more anal about iospace accesses (Sep 15, 2004) http://lwn.net/Articles/102240/ Signed-off-by: Márton Németh Signed-off-by: Grant Likely --- diff --git a/drivers/gpio/gpio-ml-ioh.c b/drivers/gpio/gpio-ml-ioh.c index af6d4f352d01..03d6dd5dcb77 100644 --- a/drivers/gpio/gpio-ml-ioh.c +++ b/drivers/gpio/gpio-ml-ioh.c @@ -248,7 +248,7 @@ static void ioh_gpio_setup(struct ioh_gpio *chip, int num_port) static int ioh_irq_type(struct irq_data *d, unsigned int type) { u32 im; - u32 *im_reg; + void __iomem *im_reg; u32 ien; u32 im_pos; int ch; @@ -412,7 +412,7 @@ static int __devinit ioh_gpio_probe(struct pci_dev *pdev, int i, j; struct ioh_gpio *chip; void __iomem *base; - void __iomem *chip_save; + void *chip_save; int irq_base; ret = pci_enable_device(pdev); @@ -521,7 +521,7 @@ static void __devexit ioh_gpio_remove(struct pci_dev *pdev) int err; int i; struct ioh_gpio *chip = pci_get_drvdata(pdev); - void __iomem *chip_save; + void *chip_save; chip_save = chip;
