From c182274ffe1277f4e7c564719a696a37cacf74ea Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 19 Jun 2006 23:59:31 -0700 Subject: [PATCH] [PATCH] USB: move usb_device_class class devices to be real devices This moves the usb class devices that control the usbfs nodes to show up in the proper place in the larger device tree. No userspace changes is needed, this is compatible due to the symlinks generated by the driver core.
