I tried several times and somehow couldn't see this. Will do more testing...

v1 configures S_FMT for whole pipeline (video, sensors thru subdevices)
thru video device node.

But based on Helen feedback for v1, removed it from video S_FMT and
added link_validate in v2.

With this user space has to configure so had to create nodes for
subdevice nodes also.

Please confirm if we want to stick with doing S_FMT configuration for
complete pipeline from video device node.

Will change back in v3.
