[media] mem2mem: set missing v4l2_dev pointer 2013-06-28T18:09:43+00:00 Hans Verkuil hans.verkuil@cisco.com 2013-06-27T05:44:04+00:00 8f484d8767d3d80bc20bb341a4b3e35894ef704b The m2m-deinterlace, mem2mem_testdev and mx2_emmaprp drivers didn't set the v4l2_dev pointer in struct video_device, even though a v4l2_device was registered correctly. These days this v4l2_dev pointer must be set correctly, so this patch adds that for these three drivers.
