From f5dccb15877b82a40950c6f752d5345c86189fc9 Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 10 Mar 2014 16:34:51 -0500 Subject: [PATCH] mfd: lpc_ich: Fix ACPI enable bitmask The original bitmask of 0x10 was incorrect and would result in a write to a reserved read-only bit instead of enabling the ACPI I/O region. Update it to the proper value of 0x80.
