Subject: media: em28xx: make v4l2-compliance happier by starting sequence on zero
Author: Mauro Carvalho Chehab <mchehab+samsung@xxxxxxxxxx>
Date: Thu Sep 13 22:46:29 2018 -0400
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.
