In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid overflow from uint32t to uint8t
[WHAT & HOW] dmubrbcmd's rampingboundary has size of uint8t and it is assigned 0xFFFF. Fix it by changing it to uint8_t with value of 0xFF.
This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.
