Subject: PNP: make pnpacpi_suspend handle errors
From: Rafael J. Wysocki <rjw@xxxxxxx>
pnpacpi_suspend() doesn't check the result returned by
acpi_pm_device_sleep_state() before passing it to acpi_bus_set_power(),
which may not be desirable. Make it select the target power state of the
device using its second argument if acpi_pm_device_sleep_state() fails.
