    ACPI: Fix D3hot v D3cold confusion · 1cc0c998
    Lin Ming authored
    Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot
    in some places, but D3cold in other places.
    After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD;
    and all references to D3hot use ACPI_STATE_D3_HOT.
    ACPI's _PR3 method is used to enter both D3hot and D3cold states.
    What distinguishes D3hot from D3cold is the presence _PR3
    (Power Resources for D3hot)  If these resources are all ON,
    then the state is D3hot.  If _PR3 is not present,
    or all _PR0 resources for the devices are OFF,
    then the state is D3cold.
    This patch applies after Linux-3.4-rc1.
    A future syntax cleanup may remove ACPI_STATE_D3
    to emphasize that it always means ACPI_STATE_D3_COLD.
