摄像头识别没问题，好像也能抓数据，数据怎么样还没看。
目前问题是 v4l2-ctl --list-devices 时报错
[ 136.480547] rkcif-dvp: get_remote_sensor: remote pad is null
[ 136.480585] rkcif-dvp: rkcif_update_sensor_info: stream[1] get remote sensor_sd failed!
[ 136.480605] rkcif_scale_ch1: update sensor info failed -19
应该会是哪方面的问题？
PS. 查看拓扑结构 media-ctl -d /dev/media0 -p
