Subject: libsmartcols: fix width= property parsing
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=351eae3efe92901aae7066c12f64ea680670a464;p=thirdparty%2Futil-linux.git

libsmartcols: fix width= property parsing

The code uses 'errno' to detect errors, but the variable is not set to
zero before parsing the number. As a result, any previous error can
affect the width number parsing.
