Alan - is this expected during normal operation on some parts, or it's
something truly unexpected/unexplained? If the former then I think it
would be good to downgrade away from drm_WARN so it is less scary.
Commit message talks about "HW/platform gaps" - if it is like a missing
BIOS support or so then I think WARN_ON is too much.
Note that this was on pre-production TGL-H HW with BIOS from April 2021.
(I don't know where to get update, nor interested to update it.)

Alan: Hi Tvrtko, thanks for the feedback -i shall change from WARN_ONCE to drm_info_once.
Maybe it deserves to be a warning? Or a notice? I was just thinking it
does not need a call trace and all since it is not a driver issue. Your
call on the level and whether or not there is any chance for it to
happen in the field to make the discussion relevant or not.
Regards,
Tvrtko
