I guess none of my concern, really, but here's a hint:

The underlying reason for me to create struct drm_edid to begin with,
make it opaque, and to go through all the trouble of converting tons of
code from struct edid to struct drm_edid was exactly the above statement
being replicated all over the place. It's fundamentally incompatible
with the HF-EEODB EDID extension block.

BR,
Jani.
