[RESEND] thermal: hwmon: Properly report critical temperature in sysfs

From: Krzysztof Kozlowski
Date: Wed Dec 28 2016 - 12:35:43 EST

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:

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().
