From: Rafael J. Wysocki <[email protected]> When a transition to the D3cold power state is requested, acpi_device_set_power() first carries out a transition to D3hot and then turns off the device's power resources. However, it fails to update the device's power.state field appropriately and D3hot is stored in it as a result.
Fix this, but make sure that the device's power.state value will be D3hot if its power resources cannot be turned off in the final step. Signed-off-by: Rafael J.
