[PATCH v3] thermal: rcar_gen3_thermal: improve logging during probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When setting up a new board, a plain "Can't register thermal zone"
didn't help me much because the thermal zones in DT were all fine. I
just had a sensor entry too much in the parent TSC node. Reword the
failure/success messages to contain the sensor number to make it easier
to understand which sensor is affected. Example output now:

rcar_gen3_thermal e6198000.thermal: Sensor 0: Loaded 1 trip points
rcar_gen3_thermal e6198000.thermal: Sensor 1: Loaded 1 trip points
rcar_gen3_thermal e6198000.thermal: Sensor 2: Loaded 1 trip points
rcar_gen3_thermal e6198000.thermal: Sensor 3: Can't register thermal zone

Change since v2:

* don't add plural-'s' at runtime to allow for a greppable string
  (Thanks, Niklas!)
