From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
The fw_trips_index[] array in struct iwl_mvm_thermal_device is only
populated, but never read, so drop it.
Note that the iwl_mvm_send_temp_report_ths_cmd() code populating
fw_trips_index[] is questionable, because it accesses a trips table
of a thermal zone directly, which is not guaranteed to work in the
future.
No functional impact.
