Subject: [PATCH 5/7] usb: gadget: fastboot: be more informative on booting
Date: Fri,  7 Dec 2018 11:34:03 +0100	[thread overview]
Message-ID: <20181207103405.27365-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20181207103405.27365-1-s.hauer@pengutronix.de>

We used to end the fastboot session once we received the boot command.
Now that we end the session during shutdown we can do better: We can
end the session once we actually shutdown, or more importantly in the
case of an error.
