Subject: [PATCH] nfnl_osf: Drop pointless check in xt_osf_strchr()

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1525980
Upstream Status: iptables commit 8c786a351a441

    nfnl_osf: Drop pointless check in xt_osf_strchr()

    Although it remains unclear what the original intention behind the
    affected code was, but 'tmp + 1' always evaluates true since 'tmp' is a
    pointer value.
