From 8f484d8767d3d80bc20bb341a4b3e35894ef704b Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 27 Jun 2013 02:44:04 -0300 Subject: [PATCH] [media] mem2mem: set missing v4l2_dev pointer 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.
