3.13.11-ckt24 -stable 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.
