Subject: irqchip/mips-cpu: Drop unnecessary static
X-Git-Tag: v4.14-rc1~413^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=82faeffa7e130e2ae43aa681a34c02d56dabd177;p=platform%2Fkernel%2Flinux-rpi.git

irqchip/mips-cpu: Drop unnecessary static

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>
