thermal: hwmon: Properly report critical temperature in sysfs
commit f37fabb8643eaf8e3b613333a72f683770c85eca upstream.
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 e68b16abd91d ("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().
Fixes: e68b16abd91d ("thermal: add hwmon sysfs I/F")
