Subject[PATCH v2 02/16] thermal/core: Show a debug message when get_temp() fails
The different thermal drivers are showing an error in case the
get_temp() fails. Actually no traces should be displayed in the
backend ops but in the call site of this ops.

Furthermore, the message is often a dev_dbg message where the
tz->device is used, thus using the internal of the structure from the

Show a debug message if the thermal_zone_get_temp() fails to read the
sensor temperature, so code showing the message is factored out and
the tz->device accesss is in the scope of the thermal core framework.
