This can equally well be handled in the .set_fmt() handler instead. Beside avoiding special cases and using the same .get_fmt() handler in all modules, it ensures that the correct format is stored in the active state for the source pad, including when .set_fmt() is called from vsp1_entity_init_state(). Both are needed to later switch to the V4L2 subdev active state API.
