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

after:
