[BK PATCH] devfs cleanups for 2.5.29

Hi,

When devfs came alone, it created devfs_[un]register_chrdev and
devfs_[un]register_blkdev, which required that all drivers be changed to
be compatible with devfs. This change has been bothering a lot of people
for quite some time :)

These two small changesets (patches to follow this email) fix that
problem by removing these functions, and having the original
[un]register_chrdev and [un]register_blkdev ask devfs if the operation
should be performed _if_ devfs is currently compiled into the kernel.
No functionality is changed, but the kernel code base is reduced, and we
are back to a common API.

If people want me to, I'd be glad to make up a patch for 2.4 that does
this same thing.

Linus, please pull from:
bk://linuxusb.bkbits.net/devfs-2.5

thanks,

greg k-h

Removed devfs_register_blkdev and devfs_unregister_blkdev.

Use register_blkdev and unregister_blkdev as before, and everything will work just fine.
