Subject: [PATCH] Bluetooth: Skip the shutdown routine if the interface is not up
Date: Sun, 26 Apr 2015 20:51:50 +0200	[thread overview]
Message-ID: <1430074310-3192-1-git-send-email-gabriele.mzt@gmail.com> (raw)

Most likely, the shutdown routine requires the interface to be up.
This is the case for BTUSB_INTEL: the routine tries to send a command
to the interface, but since this one is down, it fails and exits once
HCI_INIT_TIMEOUT has expired.
