From 0cca6e24b741c4e46cc85ff04635fe4df05cf949 Mon Sep 17 00:00:00 2001 From: Elyes HAOUAS Date: Tue, 13 Nov 2018 14:23:29 +0100 Subject: ACPI: Fix DSDT's revision field DSDT revision is =1 for ACPI v1 and =2 for greater ACPI version. This will cause the AML interpreter to use 32-bit integers and math if the version is 1, and 64-bit if the version is >=2. Current spec version is 2 for ACPI 6.2-a.
