For more details see [1] and [2]. This patch will remove the following sparse warnings ("make C=1"): * warning: incorrect type in assignment (different address spaces) * warning: incorrect type in argument 1 (different address spaces) * warning: incorrect type in argument 2 (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-pch.c b/drivers/gpio/gpio-pch.c index 7f008fb..68fa55e 100644 --- a/drivers/gpio/gpio-pch.c +++ b/drivers/gpio/gpio-pch.c @@ -231,7 +231,7 @@ static void pch_gpio_setup(struct pch_gpio *chip) static int pch_irq_type(struct irq_data *d, unsigned int type) { u32 im; - u32 *im_reg; + u32 __iomem *im_reg; u32 ien; u32 im_pos; int ch;
