| * | | Bluetooth: AMP: Use Loglink handle in ACL Handle fieldAndrei Emeltchenko2012-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For AMP HCI controller use Logical Link handle in HCI ACL Handle field.

| * | | Bluetooth: Rename __l2cap_connect() to l2cap_connect()Gustavo Padovan2012-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of "__" usually means we need to call the function with a lock held, which is not the case here. Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
| * | | Bluetooth: Add chan->ops->defer()Gustavo Padovan2012-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When DEFER_SETUP is set defer() will trigger an authorization request to the userspace. l2cap_chan_no_defer() is meant to be used when one does not want to support DEFER_SETUP (A2MP for example).

| * | | Bluetooth: Move bt_accept_enqueue() to l2cap_sock.cGustavo Padovan2012-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is part of the move the parent socket usage to l2cap_sock.c The change is safe when it comes to locking, bt_accept_enqueue() is still protected by the parent socket lock inside the l2cap_sock_new_connection_cb() code.
