From: Aaron Lu <aaron.lu@xxxxxxxxx> Date: Wed, 21 May 2014 16:00:42 +0800 Subject: [PATCH] ACPI / thermal: fix workqueue destroy order When the thermal module is to be removed, we should destroy the wq acpi_thermal_pm_queue after the ACPI driver's remove callback is executed as we will need to flush the workqueue there, or a NULL pointer access will be hit.
