From a6ff3c0021468721b96e84892a8cae24bde8d65f Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Wed, 1 Mar 2023 21:14:29 +0100 Subject: thermal/core: Add a thermal zone 'devdata' accessor The thermal zone device structure is exposed to the different drivers and obviously they access the internals while that should be restricted to the core thermal code. In order to self-encapsulate the thermal core code, we need to prevent the drivers accessing directly the thermal zone structure and provide accessor functions to deal with. Provide an accessor to the 'devdata' structure and make use of it in the different drivers. No functional changes intended. Signed-off-by: Daniel Lezcano Acked-by: Rafael J.
