From: Matthew Garrett Date: Fri, 11 May 2012 08:08:25 +0000 (+0800) Subject: ACPI: Add stubs for (un)register_acpi_bus_type X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=66886d6f8c9bcdee3d7fce5796dcffd6b4bc0b48;p=openwrt%2Fstaging%2Fblogic.git ACPI: Add stubs for (un)register_acpi_bus_type It's unreasonable to have CONFIG_ACPI for these in drivers, so add some stub functions.
