[PATCH] staging: rtl8712: Use list iterators and helpers

[Guenter Roeck]

Use existing list iterators and helper functions.

The following coccinelle script was used to convert the code.

@@
identifier v1, v2, v3, v4;
symbol next;
expression e;
iterator name list_for_each;
statement S;
@@

<+...
(
- e = v1->next;
|
- e = get_next(v1);
)
  ... when != e
- while ( \( v1 != e \| e != v1 \) )
+ list_for_each (e, v1)
  {
    ...
-   v2 = container_of(e, struct v3, v4);
+   v2 = list_entry(e, struct v3, v4);
?-  if (!v2) S
    ...
(
-   e = e->next;
|
- e = get_next(e);
)
    ... when != e
  }
...+>

Compile tested only.
