From 6cf5767c7107c606644503f3e95bc1855386a70f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 27 Jul 2009 11:38:52 -0700 Subject: drivers/atm: Correct redundant test str has already been tested. It seems that this test should be on the recently returned value snr. A simplified version of the semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // @r exists@ local idexpression x; expression E; @@ if (x == NULL || ...) { ... when forall return ...; } ... when != \(x=E\|x--\|x++\|--x\|++x\|x-=E\|x+=E\|x|=E\|x&=E\|&x\) ( *x == NULL | *x != NULL ) // Signed-off-by: Julia Lawall Signed-off-by: David S.
