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. Use the devdata accessor introduced in the previous patch. No functional changes intended.

Use the accessor in the hwmon_scmi and acpi_thermal. No functional change intented. Signed-off-by: Daniel Lezcano Acked-by: Guenter Roeck Acked-by: Rafael J.
