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
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-testing branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will be merged to the staging-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: staging: vt6655: device_rx_srv check sk_buff is NULL
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.
