| Subject: media: em28xx: make v4l2-compliance happier by starting sequence on zero |
| |
| From: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> |
| |
| 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. |
