Subject: [PATCH] Documentation: update the devices.txt documentation

Alan is no longer maintaining this list through the Linux assigned
numbers authority. Make it a collective document by referring to
"the maintainers" in plural throughout, and naming the chardev and
block layer maintainers in particular as parties of involvement.
Cut down and remove some sections that pertained to the process of
maintaining the list at lanana.org and contacting Alan directly.

Make it clear that this document, in the kernel, is the master
document.

Also move paragraphs around so as to emphasize dynamic major number
allocation.

Remove paragraph on 2.6 deprecation, that tag no longer appears
anywhere in the file.

Greg I guess this can go through the drivercore tree?

-I do, however, make a few requests about the nature of your report.

-correct in a timely manner.  First of all, *please* send it to the
-correct address... <device@...ana.org>.  I receive hundreds of email
-messages a day, so mail sent to other addresses may very well get lost
-in the avalanche.  Please put in a descriptive subject, so I can find
-your mail again should I need to.  Too many people send me email
-saying just "device number request" in the subject.

-Second, please include a description of the device *in the same format

-device and avoid conflicts.

+for a device number make sure you actually need one.
 
-Third, please don't assume that the distributed version of the list is
-up to date.  Due to the number of registrations I have to maintain it
-in "batch mode", so there is likely additional registrations that
-haven't been listed yet.
+To have a major number allocated, or a minor number in situations
+where that applies (e.g. busmice), please submit a patch and send to
+the authors as indicated above.
