In few places we have the following code pattern: int ret; ... /* @ret is not accessed here */ ret = f(...); return ret; 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.
