From 6deb00230f5df68da3ca7490402a0c537bf386bb Mon Sep 17 00:00:00 2001 From: Fu Zhonghui <zhonghui.fu@linux.intel.com> Date: Tue, 9 Sep 2014 13:02:25 +0800 Subject: [PATCH] ACPI / platform / LPSS: disable async suspend/resume of LPSS devices
LPSS devices must suspend/resume in fixed order. Or some LPSS devices will hang during the transition to ACPI_STATE_D0 state.
