From 710f11c08e9f18a8a642024880804436c0969514 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 26 May 2014 11:21:22 +0300 Subject: [PATCH] Bluetooth: Use custom macro for testing BR/EDR SC enabled Since the HCI_SC_ENABLED flag will also be used for controllers without BR/EDR Secure Connections support whenever we need to check specifically for SC for BR/EDR we also need to check that the controller actually supports it. This patch adds a convenience macro for check all the necessary conditions and converts the places in the code that need it to use it.
