Subject:
 [RESEND][PATCH v1 2/8] thermal: hisi: Use thermal_zone_for_each_trip() in
 hisi_thermal_register_sensor()

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

Modify hisi_thermal_register_sensor() to use thermal_zone_for_each_trip()
for walking trip points instead of iterating over trip indices and using
thermal_zone_get_trip() to get a struct thermal_trip pointer from a trip
index.
