+Subject: [PATCH] staging: bcm2835-codec: set device_caps in struct
+ video_device
+
+Instead of filling in the struct v4l2_capability device_caps
+field, fill in the struct video_device device_caps field.
+
+That way the V4L2 core knows what the capabilities of the
+video device are.
+
+This is similar to a cleanup series by Hans Verkuil [1].
