4 Subject: [PATCH] staging: bcm2835-codec: set device_caps in struct
5 video_device
6
7 Instead of filling in the struct v4l2_capability device_caps
8 field, fill in the struct video_device device_caps field.
9
10 That way the V4L2 core knows what the capabilities of the
11 video device are.
12
13 This is similar to a cleanup series by Hans Verkuil [1].
