CVE-2024-46871: drm/amd/display: Correct the defined value for AMDGPU_DMUB_NOTIFICATION_MAX
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Correct the defined value for AMDGPUDMUBNOTIFICATIONMAX
[Why & How] It actually exposes '6' types in enum dmubnotificationtype. Not 5. Using smaller number to create array dmubcallback & dmubthreadoffload has potential to access item out of array bound. Fix it.
