media: common: saa7146: fix compliance problems with field handling

2023-04-15T07:53:53Z

The initial field value of the format is ANY, which isn't allowed. Change to INTERLACED. VIDIOC_TRY_FMT will overwrite vv->last_field, which is an unwanted side-effect, so drop this. And finally vidioc_s_fmt_vid_cap didn't initialize vv->last_field correctly. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
