Public bug reported:
Newer VBIOS on DCN 3.5 bumped the version of IntegratedInfo table from
2.2 to 2.3. This version uses same structure. Version 2.3 is missing
from the construct_integrated_info() parser, so it leads to NULL pointer
dereference.
Fix landed to upstream v6.9-rc7: 9a35d205f466 ("drm/amd/display: Atom
Integrated System Info v2_2 for DCN35")
