From 12ad93ab6eeb0c30dbcb5df7f72415a092f6f191 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Fri, 7 Jul 2023 22:37:30 +0200 Subject: [PATCH 1/2] thermal/drivers/int3400: Use thermal zone device wrappers Use the thermal core API to access the thermal zone "type" field instead of directly using the structure field. While here, remove access to the temperature field, as this driver is reporting fake temperature, which can be replaced with INT3400_FAKE_TEMP. Also replace hardcoded 20C with INT3400_FAKE_TEMP Acked-by: srinivas pandruvada Signed-off-by: Daniel Lezcano Signed-off-by: Rafael J.

We don't want the driver to access the thermal zone device internals. Actually, the thermal core code already checks if the thermal zone's state is different before calling this function, thus this check is duplicate. Remove it.
