[PATCH 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:

Antonie: I took the liberty to fold in your patches changes to address
my comments on your v1. I pushed an un-squased version of the patches
here:

so you can easily get the diff from this and your version. Please feel
free to comment on these as you're the original author.
