I'd remove the warning. It is an optional parameter, so there is no
need to warn about something going wrong. As you say in the commit
log, it is ignored in the thermal subsystem and only used by some
sensors so no need to warn about it missing.
Other than that, I'm happy to see this merged.

As Hikey has only one voltage domain, you only have one cpu cooling
device. "contribution" is only useful when you have more than one
cooling device, as it's relative to the other cooling device's
contribution. You can remove contribution from here.
Other than this minor stuff, it looks good to me. FWIW,

My first impression was that this is redundant and you could store the
pointer to cdev in driver_data itself. But seeing that it's mirroring
the structure in cpufreq-dt and it's simpler to do it this way I guess
it's ok to create this struct with

devicetree or via thermal_zone_add_subtz() expose that relationship in

When devfreq cooling entered Eduardo's tree, the kbuild test robot
spotted a compilation warning on sh. Also, the first patch aligns the

those of the cpu cooling device.
This patches apply on top of eduardo/next.
