3.2.71-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Malcolm Priestley <tvbox...@gmail.com> commit b5eeed8cb6097c8ea660b6598d36fdbb94065a22 upstream. There is a small chance that pRD->pRDInfo->skb could go NULL while the interrupt is processing. Put NULL check on loop to break out.
