Subject[PATCH] Staging: rtl8188eu: core: Use list_for_each_entry_safe
Date
Use list_for_each_entry_safe to make the code more compact. Done 
by the following semantic patch by coccinelle.

@r@
struct list_head* l;
expression e;
identifier m,list_del_init,f;
type T1;
T1* pos;
iterator name list_for_each_entry_safe;
@@

f(...){

+T1* tmp;
<+...
-while(...)
+list_for_each_entry_safe(pos,tmp,l,m)
{
...
-pos = container_of(l,T1,m);
...
-l=e;
<+...
list_del_init(&pos->m)
...+>
}
...+>

}
