Hi Jesse,

The recently introduced pci_prepare_to_sleep() needs the following fix,
because there are systems which are not power manageable by ACPI (ie. ACPI
doesn't provide methods to put the device into low power states and back),
but require ACPI hooks to be executed for wake-up to work.

Please apply.

Thanks,
Rafael

Fix pci_prepare_to_sleep() to work on systems that are not power
manageable by ACPI (ie. ACPI doesn't provide methods to put the
device into low power states and back into the full power state), but
require ACPI hooks to be executed for wake-up to work.

Based on what you've told me so far about the number of ACPI vs. native wakeup 
methods & problems, I'm starting to get a little worried that making this 
stuff work right will require lots of platform specific quirks.  I guess 
that's just par for the course though, and this patch looks fine, so I just 
applied it to my linux-next branch.

Thanks,
Jesse
