Hi All, The ov5693 driver uses v4l2_subdev_get_try_crop() / v4l2_subdev_get_try_format() both of which are only defined if CONFIG_VIDEO_V4L2_SUBDEV_API=y . Yet it does not do select VIDEO_V4L2_SUBDEV_API in its Kconfig bits ? Note I've not seen any build errors because of this, I guess we somehow end up getting away with this... But still I think the select should be added ? Regards, Hans
