From 92d0d66c1515c8ee3b700ab3d610587c71fe497f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 2 Oct 2010 10:59:15 -0300 Subject: [PATCH] [media] drivers/media/dvb/ttpci/av7110_av.c: Add missing error handling code Extend the error handling code with operations found in other nearby error handling code. A simplified version of the sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r exists@ @r@ statement S1,S2,S3; constant C1,C2,C3; @@ *if (...) {...
