Subject: [PATCH v1] thermal: core: Drop redundant trips check from for_each_thermal_trip()
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
It is invalid to call for_each_thermal_trip() on an unregistered thermal
zone anyway, and as per thermal_zone_device_register_with_trips(), the
trips[] table must be present if num_trips is greater than zero for the
given thermal zone.
Hence, the trips check in for_each_thermal_trip() is redundant and so it
can be dropped.
