From d6e5bcf4a7ebbe258124a931f1449338340a99b5 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 20 Jun 2005 21:15:16 -0700 Subject: [PATCH] [PATCH] devfs: Remove the mode field from usb_class_driver as it's no longer needed Also fixes all drivers that set this field, and removes some other devfs specfic USB logic.
