From cebf4cfd8608cbcc941750801217988f0a8fc848 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 10 Oct 2013 18:06:04 +0200 Subject: [PATCH] Bluetooth: Fix checking for HCI_SETUP flag when receiving mgmt commands When the HCI_SETUP flag is set the controller has not yet been announced over mgmt and therefore doesn't exist from that perspective. If we nevertheless get a mgmt command for it we should respond with the appropriate INVALID_INDEX error.
