[PATCH] USB brlvger: Driver obsoleted by rewrite using usbfs

We have rewritten the brlvger (Tieman Voyager USB Braille display) driver
so that it works from user-space through usbfs. It appears to work just as
well as the in-kernel driver.

The brlvger driver in the 2.6.x kernel is now obsolete and should be
removed. The attached patch against 2.6.3 does this. Please apply.
NB: The following files are completely deleted:
    Documentation/usb/brlvger.txt
    drivers/usb/misc/brlvger.c
    include/linux/brlvger.h

The new Voyager driver is available (stil under GPL) as part of BRLTTY,
starting with version 3.5pre1 (http://mielke.cc/brltty).
Thanks to Dave Mielke who implemented BRLTTY's usbfs functionality, among
lots of other stuff.

-Kernel Driver for the Tieman Voyager Braille Display (USB)
-
-Authors:
-Stéphane Dalton <sdalton@videotron.ca>
-Stéphane Doyon  <s.doyon@videotron.ca>
-
-Version 0.8, April 17, 2002
-
-The brlvger driver supports a Braille display (aka Braille terminal)
-model Voyager from Tieman.
-
-The driver has been in heavy use for about six months now (as of April
-17th 2002) by a very few users (about 3-4), who say it has worked very
-well for them.
-
-We have tested it with a Voyager 44, but it should also support
-the Voyager 70.
-
-This driver implements a character device which allows userspace programs
-access to the braille displays raw functions. You still need a userspace
-program to perform the screen-review functions and control the
-display. Get BRLTTY from http://mielke.cc/brltty/ (version 2.99.8 or
-later). It has a Voyager driver which interfaces with this kernel driver.
-
-The interface is through a character device, major 180, minor 128, called
-"brlvger" under devfs.
-
-Many thanks to the Tieman people: Corand van Strien, Ivar Illing, Daphne
-Vogelaar and Ingrid Vogel. They provided us with a Braille display (as
-well as programming information) so that we could write this driver. They
-replaced the display when it broke and they answered our technical
-questions. It is very motivating when companies take an interest in such
-projects and are so supportive.
-
-Thanks to Andor Demarteau <ademarte@students.cs.uu.nl> who got this whole
-project started and beta-tested all our early buggy attempts.
