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.
