Subject: PNPACPI sets pnpdev->dev.archdata
From: David Brownell <[EMAIL PROTECTED]>
Teach PNPACPI how to hook up its devices to their ACPI nodes, so that
pnpdev->dev.archdata points to the parallel acpi device node. Previously
this only worked for PCI, leaving a notable hole.
Export "acpi_bus_type" so this can work.
Remove some extraneous whitespace.
