From 8b48463f89429af408ff695244dc627e1acff4f7 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Tue, 3 Dec 2013 08:49:16 +0800 Subject: ACPI: Clean up inclusions of ACPI header files Replace direct inclusions of , and , which are incorrect, with inclusions and remove some inclusions of those files that aren't necessary. First of all, , and should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that be included prior to so that the acpi_pci_root declarations the latter depends on are always there. And which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including as appropriate.
