[RFC PATCH 08/15] ACPICA: OSL: Updates ACPI_EXTERNAL_RETURN_x usages for external APIs.
From: Lv Zheng
Date: Wed Dec 18 2013 - 04:07:59 EST
OSPMs like Linux trend to include all header files but leave empty inline
stub variables for a feature that is not configured during build.
This patch configures ACPICA external APIs out and defines them into
function stubs when CONFIG_ACPI is not enabled. Lv Zheng.
