Subject: [PATCH 2/2] usb: fastboot: umount device before writing to it
Date: Wed, 8 Mar 2017 10:24:02 +0100 [thread overview]
Message-ID: <20170308092402.21245-2-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20170308092402.21245-1-o.rempel@pengutronix.de>
From: Sascha Hauer <s.hauer@pengutronix.de>
When a fastboot target refers to a device and we are going to write
to it, umount it beforehand, so that we do not end up with corrupt
data after writing.
