[ 223/262] Bluetooth: Change signature of smp_conn_security()

From: Greg Kroah-Hartman
Date: Fri Sep 28 2012 - 15:05:14 EST


From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>

3.5-stable review patch. If anyone has any objections, please let me know.

------------------

From: Vinicius Costa Gomes <vinicius.gomes@xxxxxxxxxxxxx>

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.
