Subject: [PATCH net] net: nb8800: Fix SKB leak in nb8800_receive()
Date: Fri, 15 Jul 2016 16:41:16 -0700 [thread overview]
Message-ID: <1468626084-31618-1-git-send-email-f.fainelli@gmail.com> (raw)
In case nb8800_receive() fails to allocate a fragment, we would leak the
SKB freshly allocated and just return, instead, free it.
Reported-by: coverity (CID 1341750)
