Up to you, in any case I hope to get around to adding a struct v4l2_size to address this in the future. For now I prefer to keep it as a v4l2_rect as there are other members of struct rvin_dev which would benefit from a size structure as well and having them all the same makes it easier to spot IMHO. > > Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Thanks. > > > * @std: active video standard of the video source > > * > > * @alpha: Alpha component to fill in for supported pixel formats > > @@ -215,7 +215,7 @@ struct rvin_dev { > > > > struct v4l2_rect crop; > > struct v4l2_rect compose; > > - struct v4l2_rect source; > > + struct v4l2_rect src_rect; > > v4l2_std_id std; > > > > unsigned int alpha; > > -- > Regards, > > Laurent Pinchart
