Wysocki 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. Signed-off-by: Rafael J.
