Subject: Fix possible undefined value in check-symsorting.pl
X-Git-Tag: CVE-2013-1962~179
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f7a1ac810421c084f736f77492d541301dfbd90;p=thirdparty%2Flibvirt.git

Fix possible undefined value in check-symsorting.pl

It is possible for $line to be undefined at first used, if
the symfile doesn't have a section prefix (which is the case
for auto-generated symfiles).
