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/) // <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> 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 <Julia.Lawall@lip6.fr> Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
