In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Resize MST HDCP per-connector arrays to 32 AMDGPU_DM_MAX_DISPLAY_INDEX is 31. It suggest a maximum number of 32 connectors. But the way it's used is like MAX_DISPLAY_COUNT. Hence we're off by one with DRM core, which supports a max of 32 connectors. Rename AMDGPU_DM_MAX_DISPLAY_INDEX to AMDGPU_DM_MAX_DISPLAY_COUNT to match its actual use, and increase the size to 32 to match the originally intended size.
