Description

A function prototype mismatch was found in the AMD GPU driver's DPM table callbacks. When kCFI (Control Flow Integrity) is enabled, the mismatched types cause CFI validation failures, potentially crashing the kernel.

Statement

This issue only manifests when CONFIG_CFI_CLANG is enabled, which is not a common configuration in most distributions. Without CFI enabled, the type mismatch has no runtime impact due to compatible ABI representation.
