In few places we have the following code pattern:

This pattern can be written less verbose:

return f(...);
This patch was generated with following coccinelle spatch:
@@
type T;
constant C;
expression f;
identifier ret;
@@
-T ret = C;
... when != ret
-ret = f;
-return ret;
+return f;
Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

Good stuff. I wonder if this Coccinelle tool would make my life easier
in the 'cleanup: return' patch series I sent ...
