Subject: [RFC PATCH V6 06/19] memory-hotplug: export the function acpi_bus_remove()
Date: Fri, 3 Aug 2012 15:49:08 +0800 [thread overview]
Message-ID: <1343980161-14254-7-git-send-email-wency@cn.fujitsu.com> (raw)
In-Reply-To: <1343980161-14254-1-git-send-email-wency@cn.fujitsu.com>
From: Wen Congyang <wency@cn.fujitsu.com>
The function acpi_bus_remove() can remove a acpi device from acpi device.
When a acpi device is removed, we need to call this function to remove
the acpi device from acpi bus. So export this function.
