Also make sure that the explicit_set flag\nfor ACPI_STATE_D3_COLD will be set if _PS3 is present and modify\nacpi_power_transition() to avoid accessing power resources for\nACPI_STATE_D3_COLD, because they don\u0027t exist.\n\nSecond, if PCI_D3hot is passed to acpi_pci_set_power_state() as the\ntarget state, the function will request a transition to\nACPI_STATE_D3_HOT instead of ACPI_STATE_D3. However,\nACPI_STATE_D3_HOT is now only marked as supported if the _PR3 AML\nmethod is defined for the given device, which is rare. This causes\nproblems to happen on systems where devices were successfully put\ninto ACPI D3 by pci_set_power_state(PCI_D3hot) which doesn\u0027t work\nnow. In particular, some unused graphics adapters are not turned\noff as a result.\n\nTo fix this issue restore the old behavior of\nacpi_pci_set_power_state(), which is to request a transition to\nACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) if either PCI_D3hot or\nPCI_D3cold is passed to it as the argument.\n\nThis approach is not ideal, because generally power should not\nbe removed from devices if PCI_D3hot is the target power state,\nbut since this behavior is relied on, we have no choice but to\nrestore it at the moment and spend more time on designing a\nbetter solution in the future.\n\nReferences: https://bugzilla.kernel.org/show_bug.cgi?id\u003d43228\nReported-by: rocko \u003crockorequin@hotmail.com\u003e\nReported-by: Cristian Rodríguez \u003ccrrodriguez@opensuse.org\u003e\nReported-and-tested-by: Peter \u003clekensteyn@gmail.com\u003e\nSigned-off-by: Rafael J.
