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") |

[Fix]
Fix landed to upstream v6.9-rc7: 9a35d205f466 ("drm/amd/display: Atom Integrated System Info v2_2 for DCN35")
[Test Case]
AMDGPU should then be initialized successfully without NULL pointer deref dump at boot.
[Where problems could occur]
No. New hardware revision with same data only.
[Other Info]
While this has been landed to v6.9-rc7, expect every kernel version older than that with planned support to the new VBIOS update should be fixed. So far linux/noble and linux-oem-6.8/noble are nominated by chip vendor.
