This also needs an update to the documentation, which still refers to
the old function removed in commit edd220b33f479cf9 ("thermal: core:
Drop thermal_zone_device_register()") in v6.6.:

Documentation/driver-api/thermal/power_allocator.rst:`thermal_zone_device_register()`
Documentation/driver-api/thermal/power_allocator.rst:`thermal_zone_device_register()`
(i.e., platform code), then weights
Documentation/driver-api/thermal/sysfs-api.rst:
*thermal_zone_device_register(char *type,

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
