Subject[PATCH v2 0/2] Add fine-grain temperature reporting
Date
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.
