From ce7b0f46bbf4bff8daab2dd3d878b9e72a623d09 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Mon, 20 Jun 2005 21:15:16 -0700
Subject: [PATCH] [PATCH] devfs: Remove the gendisk devfs_name field as it's no
 longer needed

And remove the now unneeded number field.
Also fixes all drivers that set these fields.

Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
