Subject: [PATCH] CAN: Use inode instead of kernel address for /proc file, CVE-2010-4565

BugLink: http://bugs.launchpad.net/bugs/765007

CVE-2010-4565

Since the socket address is just being used as a unique identifier, its
inode number is an alternative that does not leak potentially sensitive
information.

CC-ing stable because MITRE has assigned CVE-2010-4565 to the issue.

Seems clean enough.
