The ipu3-css.c also has a memset on the plane formats in the migu_css_queue_init(), but that's possibly still out of scope for this patch ('just')
struct v4l2_pix_format_mplane *const f = &queue->fmt.mpix; memset(f->reserved, 0, sizeof(f->reserved));
I can't yet see anything that clears the reserved formats on queue initialisations, so I don't think we can remove that yet unless I've missed something anyway.
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
