Subject: [PATCH] usb: gadget: fastboot: detect device if not present
Date: Mon, 17 Sep 2018 15:57:10 +0200 [thread overview]
Message-ID: <20180917135710.6088-1-s.hauer@pengutronix.de> (raw)
When a device file is not present when the fastboot gadget is created
then try to detect it before we fail. It may be that we want to write
to a device that we haven't used before.
