The issue\ncould occur when the index 'i' exceeds the number of transfer function\npoints (TRANSFER_FUNC_POINTS).\n\nThe fix adds a check to ensure 'i' is within bounds before accessing the\ntransfer function points. If 'i' is out of bounds the function returns\nfalse to indicate an error.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594
