This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.
Verified manually.
The coccinelle script that find and fixes this issue is:
// <smpl>
@@
type T;
constant C;
@@
- T ret = C;
... when != ret
- return ret;
+ return C;
// </smpl>

Should I send this a single big patch or as a set of small patches?
