From: Julia Lawall <[email protected]> Platform_get_drvdata is an accessor function, and has no purpose if its result is not used.
The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; type T; @@ - T x = platform_get_drvdata(...); ... when != x // </smpl> Signed-off-by: Julia Lawall <[email protected]> --- drivers/mtd/nand/bf5xx_nand.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/drivers/mtd/nand/bf5xx_nand.c b/drivers/mtd/nand/bf5xx_nand.c index b7a2494..b5fbd48 100644 --- a/drivers/mtd/nand/bf5xx_nand.c +++ b/drivers/mtd/nand/bf5xx_nand.c @@ -840,15 +840,11 @@ out_err_kzalloc: static int bf5xx_nand_suspend(struct platform_device *dev, pm_message_t pm) { - struct bf5xx_nand_info *info = platform_get_drvdata(dev); - return 0; } static int bf5xx_nand_resume(struct platform_device *dev) { - struct bf5xx_nand_info *info = platform_get_drvdata(dev); - return 0; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
