From b6f21dc3541a3660acfec1e789a011e6d4154173 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 12 Dec 2014 10:28:00 -0300 Subject: [PATCH] [media] cx25821: remove video output support The video output functionality never worked for this driver. Now remove the creation of the output video nodes as well to prevent users from thinking that video output is available, when it isn't. To correctly implement this the video output should use vb2 as well, and that requires rewriting the output DMA setup. But without hardware to test I am not able to do that.
