There are two HWs in mt8195. Since the two HWs run
in parallel, it is necessary to reorder the output images
to ensure that the order is consistent with the input images.

None :-)
It's all in this pull request:
https://patchwork.linuxtv.org/project/linux-media/patch/50618425-5159-4077-3d3b-6938c86ca474@xs4all.nl/
Now that rc1 has been released by Linus I expect this PR to be merged by the end of this week
(depending on Mauro's schedule).

Hans
