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].
