[PATCH v1 10/10] thermal: core: Relocate thermal zone initialization routine

Posted by Rafael J. Wysocki 1 month, 1 week ago

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Move thermal_zone_device_init() along with thermal_zone_device_check()
closer to the callers of the former, where they fit better together.

No functional impact.
