From d2ace29fa44589da51fedc06a67b3f05301f3bfd Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Mon, 18 Feb 2008 21:11:07 +0100 Subject: ieee1394: prevent device binding of raw1394, video1394, dv1394 These drivers don't need to match any unit_directory type device. They just need the id_table for module autoloading per module alias. Not binding any of these drivers allows special-purpose drivers with similar or same IDs to bind to devices. This currently only benefits out-of-tree drivers; on the other hand it is in no way detrimental to in-tree drivers.
