Subject: [PATCH v2 2/2] media: imx: imx7-media-csi: Fail on invalid type in VIDIOC_G_SELECTION
Date: Tue, 21 Mar 2023 08:27:07 +0100	[thread overview]
Message-ID: <20230321072707.678039-3-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20230321072707.678039-1-alexander.stein@ew.tq-group.com>

This device only supports video capture, so bail out if invalid
selection type is passed.
