The\nsubsequent division result overflows the u32 in variable, truncating\nto a pseudo-random positive value. When this is passed to\nltc4282_write_voltage_byte(), it is clamped to the maximum limit instead\nof zero.\n\nClamp val to 0 and to the maximum supported upper limit before the cast\nand assign the result to a 64-bit temporary variable before the division\nto avoid the underflow and an also possible overflow."
