    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":
    drivers/hwmon/lm95241.c:278:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    drivers/hwmon/lm95241.c: In function "set_max1":
    drivers/hwmon/lm95241.c:277:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    drivers/hwmon/lm95241.c: In function "set_min2":
    drivers/hwmon/lm95241.c:249:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    drivers/hwmon/lm95241.c: In function "set_min1":
    drivers/hwmon/lm95241.c:248:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    drivers/hwmon/lm95241.c: In function "set_type2":
    drivers/hwmon/lm95241.c:220:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    drivers/hwmon/lm95241.c: In function "set_type1":
    drivers/hwmon/lm95241.c:219:1: warning: ignoring return value of "strict_strtol", declared with attribute warn_unused_result
    
    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.
