From 24c457e27076beb2a85b4213642a6388eb88f240 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Wed, 2 Jul 2014 00:53:47 +0200 Subject: [PATCH] Bluetooth: Add support for hdev->set_bdaddr callback handling Some embedded controllers allow the programming of a public address and this adds vendor support for supporting OEM confguration of such addresses.
