Subject: hwmon: (adt7470) Fix writes to temperature limit registers
From: Guenter Roeck <[email protected]>
commit de12d6f4b10b21854441f5242dcb29ea96181e58 upstream.
Temperature limit registers are signed. Limits therefore need
to be clamped to (-128, 127) degrees C and not to (0, 255)
degrees C.
Without this fix, writing a limit of 128 degrees C sets the
actual limit to -128 degrees C.
