If acpi_install_notify_handler() for a bay device fails, the bay driver is superfluous. Most likely, another driver (like libata) is already caring about this device anyway. Furthermore, register_hotplug_dock_device(acpi_handle) from the dock driver must not be called twice with the same handler. This would result in an endless loop consuming 100% of CPU. So clean up and exit. Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
