From 0953075112d7626474b0bb88690f5f1ab93ec803 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 4 May 2017 22:10:54 +0200 Subject: mfd: max8925-i2c: Drop unnecessary static Drop static on a local variable, when the variable is initialized before any use, on every possible execution path through the function. The static has no benefit, and dropping it reduces the code size. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @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; // The change in code size is indicates by the following output from the size command. before: text data bss dec hex filename 2579 240 16 2835 b13 drivers/mfd/max8925-i2c.o after: text data bss dec hex filename 2531 240 8 2779 adb drivers/mfd/max8925-i2c.o Signed-off-by: Julia Lawall Acked-by: Kees Cook Signed-off-by: Lee Jones --- drivers/mfd/max8925-i2c.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/mfd/max8925-i2c.c') diff --git a/drivers/mfd/max8925-i2c.c b/drivers/mfd/max8925-i2c.c index 5c80aea3211f..10063236132c 100644 --- a/drivers/mfd/max8925-i2c.c +++ b/drivers/mfd/max8925-i2c.c @@ -151,7 +151,7 @@ static int max8925_probe(struct i2c_client *client, const struct i2c_device_id *id) { struct max8925_platform_data *pdata = dev_get_platdata(&client->dev); - static struct max8925_chip *chip; + struct max8925_chip *chip; struct device_node *node = client->dev.of_node; if (node && !pdata) { -- cgit v1.2.3
