Subject: [PATCH] Bluetooth: Check status of command complete for HCI_Reset
Date: Sun,  2 Nov 2014 02:45:58 +0100	[thread overview]
Message-ID: <1414892758-77105-1-git-send-email-marcel@holtmann.org> (raw)

When the HCI_Reset command returns, the status needs to be checked. It
is unlikely that HCI_Reset actually fails, but when it fails, it is a
bad idea to reset all values since the controller will have not reset
its values in that case.
