Subject: [PATCH 3/6] ACPI: Set D3cold state as default inferred state
Date: Tue, 17 Apr 2012 13:47:53 +0800 [thread overview]
Message-ID: <1334641676-14566-4-git-send-email-ming.m.lin@intel.com> (raw)
In-Reply-To: <1334641676-14566-1-git-send-email-ming.m.lin@intel.com>
ACPI_STATE_D3 means ACPI D3hot state which should only be returned when
power resources listed in _PR3 are 'on'.
Return ACPI D3cold state if no other state is known.
