3.2.71-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Ralf Baechle <r...@linux-mips.org>
commit d496f7842aada20c61e6044b3395383fa972872c upstream.
A ROSE socket doesn't necessarily always have a neighbour pointer so check
if the neighbour pointer is valid before dereferencing it.
