Remove unnecessary static on local variables syscon_regmap.
Such variables are initialized before being used, on every
execution path throughout the functions. The static has no
benefit and, removing it reduces the object file size.
This issue was detected using Coccinelle and the following
semantic patch:
@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;
In the following log you can see the difference in the object file size.
This log is the output of the size command, before and after the code
change:
before:
text data bss dec hex filename
3339 2104 128 5571 15c3 drivers/soc/versatile/soc-realview.o
after:
text data bss dec hex filename
3321 2048 64 5433 1539 drivers/soc/versatile/soc-realview.o
