This is a preparation patch for fixing ov2680_set_fmt() which == V4L2_SUBDEV_FORMAT_TRY calls not properly filling in the passed in v4l2_mbus_framefmt struct. Note that for ov2680_init_cfg() this now simply always fills the try_fmt struct of the passed in sd_state. This is correct because ov2680_init_cfg() is never called with a NULL sd_state so the old sd_state check is not necessary.
