Subject: [patch 21/26] drivers/scsi/bfa/bfad_im.c: eliminate useless code
Date: Thu, 11 Mar 2010 14:09:55 -0800 [thread overview]
Message-ID: <201003112209.o2BM9tkd013676@imap1.linux-foundation.org> (raw)
From: Julia Lawall <julia@diku.dk>
The variable bfa_itnim 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>
