commit 3620f2f2f39e7870cf1a4fb2e34063a142f28716 sets the cid of
ACPI video/dock/bay device and leaves the hid empty.
As a result, "modalias" should export the cid for
devices which don't have a hid.
ACPI Video driver is not autoloaded with

diff 3620f2f2f39e7870cf1a4fb2e34063a142f28716 Fri Dec 07 06:20:34 CST 2007 Frank Seidel <fseidel@suse.de> ACPI: Fix autloading of dock, video, bay and all linux specific HID drivers
References: https://bugzilla.novell.com/show_bug.cgi?id=302482
Due to the new autloading of acpi drivers, the dock driver
wasn't loaded anymore as there is no HID to identify it with
(dock is needed if ACPI has a _DCK method).
This patch is a workaround for this, original by Thomas Renninger,
revised first by Kay Sievers and last by Frank Seidel.
V2 of this patch fixed problems on systems without a defined _CID for
the docking devices.
