From 39558030fd684e839c09658b01d96473c13a91d3 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Tue, 15 Sep 2020 15:36:48 -0700 Subject: thermal: int340x: Provide notification for OEM variable change When we receive ACPI notification for OEM variable change pass the notification to user space handler. This will avoid polling for OEM variable change from user space.
