From a23aff365186ea8859e1c1c1b0f51f7566f231e9 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sun, 21 Jun 2020 20:47:54 +0200 Subject: src: Report byte-sized access for GPE0 According to the ACPI specification, version 6.3: OSPM accesses GPE registers through byte accesses (regardless of their length). So, reporting dword-sized access is wrong and means nothing anyway. Tested on Asus P8Z77-V LX2, Windows 10 still boots.
