[PATCH v3 03/14] thermal: core: Drop redundant thermal instance checks
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Because the trip and cdev pointers are sufficient to identify a thermal
instance holding them unambiguously, drop the additional thermal zone
checks from two loops walking the list of thermal instances in a
thermal zone.
No intentional functional impact.
