From 4202066c6995200b2755a4501ea90f5d4e163e41 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 27 May 2010 09:36:45 -0300 Subject: V4L/DVB: drivers/media: Eliminate a NULL pointer dereference In each case, the print involves dereferencing a value that is NULL or is near NULL. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r exists@ expression E,E1; identifier f; statement S1,S2,S3; @@ if ((E == NULL && ...) || ...) { ... when != if (...)
