ACPI: fix a regression of ACPI device driver autoloading 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 commit 3620f2f2f39e7870cf1a4fb2e34063a142f28716 applied. "cat /sys/.../device:03(acpi video bus)/modalias" shows nothing. ACPI Video driver is autoloaded after revert that commit. "cat /sys/.../LNXVIDEO:0x/modalias" shows "acpi:LNXVIDEO:" ACPI Video driver is autoloaded with commit 3620f2f2f39e7870cf1a4fb2e34063a142f28716 and this patch applied.
