| Subject | [PATCH 05/11] irqchip/gic/realview: Drop unnecessary static |
| Message-ID | <u3C13-64w-5@gated-at.bofh.it> |
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>
