Julia Lawall 6c51a52eeb mtd: physmap_of: 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
    835      80       8     923     39b drivers/mtd/maps/physmap_of_gemini.o

after:
   text    data     bss     dec     hex filename
    823      80       0     903     387 drivers/mtd/maps/physmap_of_gemini.o
