Hi everyone,

Here's another round addressing Hans' feedback. More details
about this can be found in the previous cover letter [1]:

[1] https://lore.kernel.org/linux-media/20210403180756.175881-11-ezequiel@collabora.com/T/

The documentation looks good, and so does pahole,
but it's really easy to miss some detail in this series,
so we'd appreciate if more people could take a look.

v6: 
* Reorder patch "media: controls: Log MPEG-2 stateless control in .std_log"
  to avoid a new compile warning.
* Remove "reserved" field in mpeg2 sequence control, noted by Hans.
* Reorder "flags" field in mpeg2 picture control, noted by Hans.
* Typos and comments fixes, noted by Hans.

v5:
* Rename "quantization" to "quantisation", so the terminology
  matches the MPEG-2 specification.
  This is the only change in v5, compared to v4.

v4:
* Rework and clarify quantization matrices control semantics.
* Move reference buffer fields to the picture parameter control.
* Remove slice parameters control. This can be added back in the
  future if needed, but for now it's not used.
  See patch 6/9 for details.
* Destage the API.

v3:
* No API changes, just minor boilerplate fixes for the new
  controls to be properly exposed, initialized and validated.

v2:
* Fixed bad use of boolean negation in a flag, which
  was fortunately reported by 0day bot.
