[PATCH v2 1/3] thermal/core: Encapsulate the trip point crossed function

From: Daniel Lezcano
Date: Fri Jul 08 2022 - 14:32:41 EST


The routine where the trip point crossed is detected is a strategic
place where different processing will happen. Encapsulate the code in
a function, so all specific actions related with a trip point crossed
can be grouped.
