The shutdown method is used by the winbond cir driver to setup the
hardware for wake-from-S5.
Changes since last version: the previous patch added a shutdown method
to acpi drivers, the winbond cir driver is now a pnp driver so the
shutdown method is added to pnp drivers instead. Patch by
Bjorn Helgaas <bjorn.helgaas@xxxxxx>.
