[PATCH 1/5] thermal/core: Rearm the monitoring only one time

From: Daniel Lezcano
Date: Fri Aug 05 2022 - 11:38:52 EST


The current code calls monitor_thermal_zone() inside the
handle_thermal_trip() function. But this one is called in a loop for
each trip point which means the monitoring is rearmed several times
for nothing (assuming there could be several passive and active trip
points).

Move the monitor_thermal_zone() function out of the
handle_thermal_trip() function and after the thermal trip loop, so the
timer will be disabled or rearmed one time.
