From c6beca0e0dc70c439894337e82609ec3b79ed900 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 17 Feb 2014 09:21:19 -0800 Subject: [PATCH] Bluetooth: Allow HCI User Channel usage for controllers without address Trying to setup HCI User Channel usage for LE only controllers without a public address or configured static address will fail with an error saying that no address is available. In case of HCI User Channel the requirement for a valid address is not needed. So allow skipping this extra validation step.
