[PATCH 1/2] ACPI: reintroduce acpi_device_ops .shutdown method

From: David HÃrdeman
Date: Sat Jun 27 2009 - 01:19:30 EST


This reintroduces the .shutdown method which is used by the
winbond-cir driver. A normal revert wasn't possible since there
had been other changes to include/acpi/acpi_bus.h since.
