Subject: [PATCH 2/9] drivers/misc: Eliminate useless code
Date: Sat, 16 Jan 2010 16:57:39 +0100 (CET) [thread overview]
Message-ID: <Pine.LNX.4.64.1001161657170.28745@ask.diku.dk> (raw)
From: Julia Lawall <julia@diku.dk>
The variable priv is initialized twice to the same (side effect-free)
expression. Drop one initialization.
A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)
// <smpl>
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@
x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)
|
* x = f(...)
)
// </smpl>
