2024-10-28media: pci: drop vb2_ops_wait_prepare/finishHans Verkuil
Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com>

2023-08-14media: bttv: move vbi_skip/vbi_count out of bufferDeborah Brouwer
Instead of storing vbi_skip and vbi_count in each bttv buffer separately, move them to the main bttv struct as they won't change per buffer. Signed-off-by: Deborah Brouwer <deborah.brouwer@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2023-08-14media: bttv: copy vbi_fmt from bttv_fhDeborah Brouwer
In preparation for the vb2 conversion, copy the vbi format from struct bttv_fh and add it to the main struct bttv. Use vbi format from struct bttv wherever it will be needed after the vb2 conversion which stops using separate bttv file handles altogether. To avoid changing more code than necessary, just leave the vbi format in separate file handles wherever it will be subsequently removed by vb2.

Both BUG and BUG_ON are replaced with WARN_ON wherever they would still be present after the vb2 conversion. WARN_ON is sufficient in these cases. Signed-off-by: Deborah Brouwer <deborah.brouwer@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
