Subject: [PATCH v2 3/5] usb: gadget: uvc: set v4l2_dev->dev in f_uvc
Date: Mon, 28 Jun 2021 10:15:58 +0200	[thread overview]
Message-ID: <20210628081600.14525-4-m.grzeschik@pengutronix.de> (raw)
In-Reply-To: <20210628081600.14525-1-m.grzeschik@pengutronix.de>

The v4l2_dev has no corresponding device to it. We will
point it to the gadget's dev.
