One more thing, sometimes we want to assign the handle like in the case of
SPI controller driver we set the master->dev.acpi_handle. In that case we
can't use DEVICE_ACPI_HANDLE() as is. Should we just do something like:

	master->dev.acpi_handle = pdev->dev.acpi_handle;

or should we introduce some new macro that supports this?

Or we could just drop the cast from the macro and use the same.

	#define DEVICE_ACPI_HANDLE(dev)	((dev)->acpi_handle)

Well, I'm not sure.  Perhaps it's better to add a new macro, like
ACPI_HANDLE(dev), defined as above and use it going forward (we can then
phase out the old one gradually).

Yeah, that sounds good.

However, let's leave the patches in this series as they are for now, we can
add that macro in a separate patch later.

OK.
