Subject: netfilter 29/29: fix warning in net/netfilter/nf_conntrack_ftp.c

commit d6e8cc6cc7ac77b0f9118f78c453a2e834e62709
Author: Ingo Molnar <mingo@...e.hu>

    netfilter: fix warning in net/netfilter/nf_conntrack_ftp.c
    
    this warning:
    
      net/netfilter/nf_conntrack_ftp.c: In function 'help':
      net/netfilter/nf_conntrack_ftp.c:360: warning: 'matchoff' may be used uninitialized in this function
      net/netfilter/nf_conntrack_ftp.c:360: warning: 'matchlen' may be used uninitialized in this function
    
    triggers because GCC does not recognize the (correct) error flow
    between find_pattern(), 'found', 'matchoff' and 'matchlen'.
    
    Annotate it.
