    This clears the following build-time warnings I was seeing:
    
    drivers/hwmon/lm95241.c: In function "set_interval":
    drivers/hwmon/lm95241.c:132:15: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    drivers/hwmon/lm95241.c: In function "set_max2":

    This also fixes a small race in set_interval() as a side effect: by
    working with a temporary local variable we prevent data->interval from
    being accessed at a time it contains the interval value in the wrong
    unit.
