This is a note to let you know that I've just added the patch titled

staging: vt6655: device_rx_srv check sk_buff is NULL

to my staging git tree which can be found at

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.
