[GIT,PULL,FOR,v5.19] v2: H.264 Field Decoding Support for Frame-based Decoders

This PR contains this Nicolas' v4 patch series:

https://patchwork.linuxtv.org/project/linux-media/patch/20220426125751.108293-2-nicolas.dufresne@collabora.com/

except for patch 03/24 ("media: videobuf2-v4l2: Warn on holding buffers without support")
which needs more work. It's independent of the other patches though, so that can be
done later.

Regards,

	Hans

Changes since v1:

- patch "Use v4l2_h264_reference for reflist" failed to compile: the tegra-vde change used
  a field that was only added 3 patches later ("Store all fields into the unordered list").
  Keep the old field and only update it in the later patch.


The following changes since commit 02970914dbc7152d6de615127261e778ef425a09:
