[PATCH v3 0/6] media: v4l2-isp: Add support for extensible statistics

[Jacopo Mondi <jacopo.mondi@ideasonboard.com>]

This series breaks out from Antonie's
https://patchwork.linuxtv.org/project/linux-media/list/?series=24043
the extensible stats support and adds a few more patches on top to:

- add support for per-block validation as suggested during the review of
  Ricardo's
  https://patchwork.linuxtv.org/project/linux-media/patch/20260504-smatch-7-1-v3-6-fda125c30058@chromium.org/

- add two helper functions to v4l2-isp to ease handling of extensible
  statistics for drivers. An early user, based on a preliminary version
  of the patches is available here as a reference:
  https://patchwork.linuxtv.org/project/linux-media/list/?series=24703

After testing v2 on real hw, I realized I had a wrong check for the
validation callback, which is now fixed in v3.

   -          if (type_info->block_validate &&
   -              type_info->block_validate(dev, block))
   +          if (info->block_validate && info->block_validate(dev, block))

and validation is now actually performed :)
