Jean Delvare 90f4102ce5 hwmon: Use i2c_smbus_{read,write}_word_swapped
Make use of the new i2c_smbus_{read,write}_word_swapped functions.
This makes the driver code more compact and readable. It also ensures
proper error handling.

Jean Delvare 774466add7 hwmon: (jc42) Change detection class
While the JC42-compatible chips are temperature sensors, I2C_CLASS_SPD
makes more sense because these chips always live on memory modules.

Clemens Ladisch 2c6315da6a hwmon: (jc42) do not allow writing to locked registers
On systems where the temperature sensor is actually used, the BIOS is
likely to have locked the alarm registers.  In that case, all writes
through the corresponding sysfs files would be silently ignored.

To prevent this, detect the locks and make the affected sysfs files
read-only.

Clemens Ladisch e866729605 hwmon: (jc42) fix type mismatch
In set_temp_crit_hyst(), make the variable 'val' have the correct
type for strict_strtoul().
