That's just a straight mistake on those formats - they should be 1. My bad for not spotting it in review. On the one hand, having formats in this table is a nice machine-readable way to describe them. On the other, as drm_fourcc is being used as the canonical repository for formats, including ones not used in DRM, we can end up with situations like this. (R10/R12 being another example of formats not used in DRM: 20211027233140.12268-1-laurent.pinchart@xxxxxxxxxxxxxxxx) Thanks, -Brian
