3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vinicius Costa Gomes <vinicius.go...@openbossa.org>
commit cc110922da7e902b62d18641a370fec01a9fa794 upstream.
To make it clear that it may be called from contexts that may not have
any knowledge of L2CAP, we change the connection parameter, to receive
a hci_conn.
This also makes it clear that it is checking the security of the link.
