From 2147439889d33148785d20cdff01491f5617965f Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 29 May 2013 09:51:29 +0300 Subject: Bluetooth: Fix mgmt handling of power on failures commit 96570ffcca0b872dc8626e97569d2697f374d868 upstream. If hci_dev_open fails we need to ensure that the corresponding mgmt_set_powered command gets an appropriate response. This patch fixes the missing response by adding a new mgmt_set_powered_failed function that's used to indicate a power on failure to mgmt. Since a situation with the device being rfkilled may require special handling in user space the patch uses a new dedicated mgmt status code for this.
