Subject: clk: mmp: Drop unnecessary static
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4aafe9c603029b7e3e91707875beef9950ba35c5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

clk: mmp: 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>
