From: Frank Schaefer Date: Mon, 24 Mar 2014 19:33:12 +0000 (-0300) Subject: upstream: [media] em28xx: move video_device structs from struct em28xx to struct... X-Git-Tag: submit/tizen/20141121.110247~743 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3adac5143e7a34eae23c29f03cb99f3db74f19dc;p=platform%2Fkernel%2Flinux-3.10.git upstream: [media] em28xx: move video_device structs from struct em28xx to struct v4l2 There are 3 struct video_device at the em28xx common struct, for video, VBI and radio. They all are used only by the V4L2 driver. So, move them to the v4l2-specific struct.
