    thermal: hwmon: Properly report critical temperature in sysfs · b4fa7414

    In the critical sysfs entry the thermal hwmon was returning wrong
    temperature to the user-space.  It was reporting the temperature of the
    first trip point instead of the temperature of critical trip point.
    
    For example:
    	/sys/class/hwmon/hwmon0/temp1_crit:50000
    	/sys/class/thermal/thermal_zone0/trip_point_0_temp:50000
    	/sys/class/thermal/thermal_zone0/trip_point_0_type:active
    	/sys/class/thermal/thermal_zone0/trip_point_3_temp:120000
    	/sys/class/thermal/thermal_zone0/trip_point_3_type:critical
    
    Since commit e68b16ab ("thermal: add hwmon sysfs I/F") the driver
    have been registering a sysfs entry if get_crit_temp() callback was
    provided.  However when accessed, it was calling get_trip_temp() instead
    of the get_crit_temp().
