      hwmon: (lm77) Prevent overflow problem when writing large limits · 99765db2
      Axel Lin authored
      On platforms with sizeof(int) < sizeof(long), writing a temperature
      limit larger than MAXINT will result in unpredictable limit values
      written to the chip.
      Clamp the input values to the supported limits first to fix the problem.
      
      For set_temp_hyst:
      As Guenter pointed out that the temperature is read as unsigned and stored in
      an unsigned long. This is wrong; nothing in the datasheet suggests that the
      value (the absolute temperature) must be positive.
      So change it to signed.
