From 12a4d05b9e35f2fd468b1667253ade1cddca415d Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Tue, 14 Jul 2020 01:31:27 +0200 Subject: src: Report word-sized access for PM1a_EVT According to the ACPI specification, version 6.3: Accesses to the PM1 status registers are done through byte or word accesses. The same is said about the PM1 Enable registers. Therefore, reporting dword-sized access is wrong and means nothing anyway. Since some other platforms use word-sized access, use word everywhere for consistency. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.
