Hi folks,
This series adjusts the temp_get() interface in the thermal functions to report milli-degrees, and additionally alters the way errors are reported. As I went through all the users and implementations I realized that Pascal's temp_get() implementation didn't include turning negative temperatures to 0 like other implementations, so I separated error reporting from the temperature in the API.
Couple of things I'm on the fence about here:
* I allowed the nvkm_therm_temp_get() functions to accept NULL as a way to check if temperature reading is available rather than adding a separate helper, but was torn about whether this is clearer than a separate helper function.
* I added a WARN_ON in places that previously called nvkm_therm_temp_get() and didn't check the return value for an error. This may not be a reasonable error handling method.
