Subject: [RFC PATCH 22/26] cxgb4: Migrate to thermal_zone_device_register()
Date: Thu, 21 Dec 2023 13:48:21 +0100

The thermal API has a new thermal_zone_device_register() function which
is deprecating the older thermal_zone_device_register_with_trips() and
thermal_tripless_zone_device_register().

Migrate to the new thermal zone device registration function.
