   4 Subject: [PATCH 745/782] 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].
