Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit.
The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- These patches are all independent of each other. drivers/mtd/maps/physmap_of_versatile.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -u -p a/drivers/mtd/maps/physmap_of_versatile.c b/drivers/mtd/maps/physmap_of_versatile.c --- a/drivers/mtd/maps/physmap_of_versatile.c +++ b/drivers/mtd/maps/physmap_of_versatile.c @@ -97,7 +97,7 @@ static const struct of_device_id ebi_mat static int ap_flash_init(struct platform_device *pdev) { struct device_node *ebi; - static void __iomem *ebi_base; + void __iomem *ebi_base; u32 val; int ret;
