From 85303db36b6e170917a7bc6aae4898c31a5272a0 Mon Sep 17 00:00:00 2001 From: Shravan S Date: Wed, 6 Oct 2021 13:05:25 +0530 Subject: [PATCH] platform/x86: int1092: Fix non sequential device mode handling SAR information from BIOS may come in non sequential pattern. To overcome the issue, a check is made to extract the right SAR information using the device mode which is currently being used. Remove .owner field if calls are used which set it automatically.
