Subject: [S390] Initialize interval value to 0.
X-Git-Tag: v2.6.19-rc4~31^2~4
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=95425f19beed99cb9b0a79f69731eda907d9db99;p=linux-2.6-omap-h63xx.git

[S390] Initialize interval value to 0.

sscanf() could leave the interval value unchanged in which case it
would be used uninitialized.
