  - drm/amd/display: Fix index out of bounds in degamma hardware format translation Fixes index out of bounds
    issue in `cm_helper_translate_curve_to_degamma_hw_format` function. The issue could occur when the index
    'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure
    'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds the function
    returns false to indicate an error. Reported by smatch:
