Subject: staging: vt6655: device_rx_srv check sk_buff is NULL

From: Malcolm Priestley <[email protected]>

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.
