[Intel-gfx] [PATCH] drm/i915: Fix not finding the VBT when it overlaps with OPREGION_ASLE_EXT

[Hans de Goede]

Hi Jani,

So any further update on this ? I've just got a report from
an user that my fix also fixes the LCD panel on his (different
model, ACER SW5_017) machine not lighting up:

https://bugzilla.kernel.org/show_bug.cgi?id=155241#c56

Although my fix my be in contradiction with the VBT spec,
I do not see how it can really hurt, it just allows the
VBT to extend into an unused part of the opregion.

Something which windows 10 apparently allows, otherwise
we would not have multiple models shipping with this
problem, so it seems best to just allow this in Linux
too.

Regards,

Hans
