Hello Samuel Ortiz,
This is a semi-automatic email about new static checker warnings.
The patch d646960f7986: "NFC: Initial LLCP support" from Dec 14,
2011, leads to the following Smatch complaint:
net/nfc/llcp/sock.c +47 llcp_sock_bind()
warn: variable dereferenced before check 'addr' (see line 45)
net/nfc/llcp/sock.c
44
45 pr_debug("sk %p addr %p family %d\n", sk, addr, addr->sa_family);
^^^^^^^^^^^^^^^
New dereference.
46
47 if (!addr || addr->sa_family != AF_NFC)
^^^^
New check.
48 return -EINVAL;
49
regards,
dan carpenter
