From e06bf91b59d3d95359e046ffcdc577145933da10 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 11 Feb 2015 17:33:23 +0100 Subject: Revert "ACPI / EC: Add GPE reference counting debugging messages" Revert commit b5bca896ef3c (ACPI / EC: Add GPE reference counting debugging messages), because it depends on commit f252cb09e1cb (ACPI / EC: Add query flushing support) which breaks system suspend on Acer Aspire S5 and needs to be reverted.
