Subject: [PATCH 7/11] bnx2x: Remove useless return variables
Date: Sat, 31 May 2014 10:14:07 -0300 [thread overview]
Message-ID: <1401542051-3174-7-git-send-email-peter.senna@gmail.com> (raw)
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 by compilation only.
The coccinelle script that find and fixes this issue is:
// <smpl>
@@
type T;
constant C;
identifier ret;
@@
- T ret = C;
... when != ret
when strict
return
- ret
+ C
;
// </smpl>
