Re: ADT746X: logical-bitwise & confusion in set_max_duty_at_crit()

It includes suggested changes by Segher Boessenkool and I think this
version was tested by Darrick J. Wong

- u8 reg;
+ u8 reg, temp;
struct i2c_client *client = to_i2c_client(dev);
struct adt7473_data *data = i2c_get_clientdata(client);
- int temp = simple_strtol(buf, NULL, 10);
- temp = temp && 0xFF;
+
+ temp = simple_strtol(buf, NULL, 10) & 0xFF;

It still does this superfluous "& 0xff", which hides the lack of
range checking.
