hwmon: (tmp401) Simplification and cleanup
Use two-dimensional array pointing to registers Merge temperature and limit access functions into a single function Return error codes from I2C reads Use DIV_ROUND_CLOSEST for rounding operations and improve rounding Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
