The v4l2_subdev_link_validate() function is a helper designed to validate links whose sink is a subdev. When called on a link whose sink is a video device, it only prints a warning and returns. As the microchip-isc driver implements manual validate of the subdev to video device link, we can just dropp the v4l2_subdev_link_validate() to avoid the warning.
