Subject: Bluetooth: Use custom macro for testing BR/EDR SC enabled
X-Git-Tag: v3.19-rc1~118^2~28^2~5^2~86
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=710f11c08e9f18a8a642024880804436c0969514;p=karo-tx-linux.git

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.
