It suggest a maximum number of\n32 connectors. But the way it's used is like MAX_DISPLAY_COUNT.\nHence we're off by one with DRM core, which supports a max of 32\nconnectors.\n\nRename AMDGPU_DM_MAX_DISPLAY_INDEX to AMDGPU_DM_MAX_DISPLAY_COUNT\nto match its actual use, and increase the size to 32 to match the\noriginally intended size.",
