Subsystem: drm drivers, radeon and amdgpu drm drivers, the rest · Maintainers: David Airlie, Simona Vetter, Alex Deucher, Christian König, Linus Torvalds

Seems like newer cards can have even more instances now.
Found by UBSAN: array-index-out-of-bounds in

index 8 is out of range for type 'uint32_t *[8]'
