The function jz_nand_ioremap_resource() needs a pointer to an __iomem pointer as its last argument but this argument is declared as: void * __iomem *base Fix this by using the correct declaration: void __iomem **base which then also removes the following Sparse's warnings: 282:15: warning: incorrect type in assignment (different address spaces) 282:15: expected void *[noderef] <asn:2> 282:15: got void [noderef] <asn:2> * 322:57: warning: incorrect type in argument 4 (different address spaces) 322:57: expected void *[noderef] <asn:2> *base 322:57: got void [noderef] <asn:2> ** 402:67: warning: incorrect type in argument 4 (different address spaces) 402:67: expected void *[noderef] <asn:2> *base 402:67: got void [noderef] <asn:2> ** Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx> --- drivers/mtd/nand/raw/jz4740_nand.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/mtd/nand/raw/jz4740_nand.c b/drivers/mtd/nand/raw/jz4740_nand.c index f92ae5aa2..9526d5b23 100644 --- a/drivers/mtd/nand/raw/jz4740_nand.c +++ b/drivers/mtd/nand/raw/jz4740_nand.c @@ -260,7 +260,7 @@ static int jz_nand_correct_ecc_rs(struct nand_chip *chip, uint8_t *dat, } static int jz_nand_ioremap_resource(struct platform_device *pdev, - const char *name, struct resource **res, void *__iomem *base) + const char *name, struct resource **res, void __iomem **base) { int ret; -- 2.20.0 ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
