From c764c9ade6d9b710bad2b9c631ede9864333b98c Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Tue, 5 Jun 2007 12:56:53 -0700 Subject: [NETFILTER]: nf_conntrack_amanda: fix textsearch_prepare() error check The return value from textsearch_prepare() needs to be checked by IS_ERR(). Because it returns error code as a pointer. Cc: "Brian J. Murrell" Signed-off-by: Akinobu Mita Signed-off-by: Patrick McHardy Signed-off-by: David S.
