Subject: [PATCH] ACPI suspend: Execute _WAK with the right argument

From: Rafael J. Wysocki <rjw@...k.pl>

The _WAK global ACPI control method has to be called with the
argument representing the sleep state being exited.  Make it happen.

Special thanks to Mirco Tischler <mt-ml@....de> for reporting the
problem and debugging.
