This patch merges an assignment with an immediately following return of
the assigned variable.  The following Coccinelle semantic patch was used
to make this transformation:

@@
expression ret;
identifier f;
@@

-ret =
+return
     f(...);
-return ret;

A variable that became unused due to this transformation was also removed.
