From 686ebf283ba19f82abd8aaec023cd124749be9ec Mon Sep 17 00:00:00 2001 From: Ulisses Furquim Date: Wed, 21 Dec 2011 10:11:33 -0200 Subject: Bluetooth: Make HCI call directly into SCO and L2CAP event functions The struct hci_proto and all related register/unregister and dispatching code was removed. HCI core code now call directly the SCO and L2CAP event functions. Signed-off-by: Ulisses Furquim Acked-by: Marcel Holtmann Signed-off-by: Gustavo F.
