PCI PM: Fix hibernation breakage on EeePC 701
Hibernation breaks on EeePC 701 as a result of attempting to put one of its (driverless) devices into a low power state. Avoid that by not attepmting to power manage driverless devices during hibernation. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Reported-and-tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
