From: Yasuaki Ishimatsu Subject: [PATCH 1/2] acpi,memory-hotplug : export the function acpi_bus_remove() Date: Thu, 4 Oct 2012 10:46:56 +0900 Message-ID: <506CEA90.4020309@jp.fujitsu.com> References: <506CE9F5.8020809@jp.fujitsu.com> Mime-Version: 1.0 Content-Type: text/plain; charset="ISO-2022-JP" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <506CE9F5.8020809@jp.fujitsu.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org, linux-mm@kvack.org Cc: len.brown@intel.com, wency@cn.fujitsu.com List-Id: linux-acpi@vger.kernel.org From: Wen Congyang The function acpi_bus_remove() can remove a acpi device from acpi bus. When a acpi device is removed, we need to call this function to remove the acpi device from acpi bus. So export this function.
