From 72a364cb4991dd08c079d68582ca5e9d90f6c32a Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 13 Sep 2018 22:46:29 -0400 Subject: [PATCH] media: em28xx: make v4l2-compliance happier by starting sequence on zero commit afeaade90db4c5dab93f326d9582be1d5954a198 upstream. The v4l2-compliance tool complains if a video doesn't start with a zero sequence number. While this shouldn't cause any real problem for apps, let's make it happier, in order to better check the v4l2-compliance differences before and after patchsets. This is actually an old issue. It is there since at least its videobuf2 conversion, e. g. changeset 3829fadc461 ("[media] em28xx: convert to videobuf2"), if VB1 wouldn't suffer from the same issue.
