Seems like there is a lot more that could be cleared in core ... But - as I said, I think that's out of scope here so Reviewed-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> > @@ -773,9 +773,6 @@ static int imgu_try_fmt(struct file *file, void *fh, struct v4l2_format *f) > > pixm->pixelformat = fmt->fourcc; > > - memset(pixm->plane_fmt[0].reserved, 0, > - sizeof(pixm->plane_fmt[0].reserved)); > - > return 0; > } > >

Core code already clears reserved fields of struct v4l2_pix_format_mplane, check: 4e1e0eb0e074 ("media: v4l2-ioctl: Zero v4l2_plane_pix_format reserved fields").
