From c74e83a8632fd88560a533980a0d4c3922325326 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 17 May 2007 06:41:44 -0300 Subject: [PATCH] V4L/DVB (5670): Adding new fields to v4l2_pix_format broke the ABI, reverted that change Reverted the change to struct v4l2_pix_format. I completely missed that this struct was used by existing ioctls so that changing it broke the ABI. I will have to think of another way of setting the top/left coordinates but for now this change is reverted to preserve compatibility.
