Hmm, but note that in the same function there is
drm_mode_validate_size() and drm_mode_validate_flag() calls,
which take as first argument the mode and then the object to
validate (I hadn't seen this). So, maybe leave it as
drm_mode_validate_connector() as it takes a connector as argument
or change to drm_mode_validate_pipeline() as you said, or even
drm_mode_validate_datapath(), drm_mode_validate_videopath(),
drm_mode_validate_components() ?
