From ee98f4738050bb93823ce9ba849f5d78f5b8c1a1 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 9 Jan 2013 15:29:36 +0200 Subject: [PATCH] Bluetooth: Fix accepting set_dev_class for non-BR/EDR controllers The concept of Class of Device only exists for BR/EDR controllers. The mgmt_set_dev_class command should therefore return a proper "not supported" error if it is attempted for a controller that doesn't support BR/EDR (e.g. a single mode LE-only one).
