[PATCH 1/1] thermal: setup monitor only once after handling trips

[PATCH 1/1] thermal: setup monitor only once after handling trips

[Eduardo Valentin]

Instead of changing the monitoring setup every time after
handling each trip, this patch simplifies the monitoring
setup by moving the setup call to a place where all
trips have been treated already.

BTW, thermal_notify_framework might need be affected?

Yeah, I can amend this.

Well, the original code does not call thermal_notify_framework. Calling
it would require a different patch. This one is just to simplify the
monitoring setup.
