From d83dc9ce57a746a6dca28439bcc0575d26fa6986 Mon Sep 17 00:00:00 2001 From: Pengpeng Hou Date: Tue, 23 Jun 2026 09:51:40 +0800 Subject: [PATCH] thermal: intel: int3400: clean up ODVP on probe failures evaluate_odvp() creates per-ODVP sysfs files before the thermal zone and later probe resources are registered. The current unwind path only calls cleanup_odvp() from the late sysfs failure path, so failures after evaluate_odvp() but before that label, including thermal_tripless_zone_device_register() failures, leave the ODVP files and storage behind. Move the ODVP cleanup to the common ART/TRT unwind path so every failure after evaluate_odvp() releases the ODVP state. Also clear the cached ODVP pointers in cleanup_odvp(), because evaluate_odvp() can already call it for partial setup failures while probe continues.
