Subject: [PATCH 3/3] ACPI / PM: Use ACPI_STATE_D3_COLD instead of ACPI_STATE_D3 everywhere
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
There are several places in the tree where ACPI_STATE_D3 is used
instead of ACPI_STATE_D3_COLD which should be used instead for
clarity. Modify them all to use ACPI_STATE_D3_COLD as appropriate.
[The definition of ACPI_STATE_D3 itself cannot go away at this point
as it is part of ACPICA.]
