Linux nnpfs devfs patch

[Per Olofsson]

Under Linux, if nnpfs is compiled with devfs support, it doesn't
register a legacy chrdev. This is a problem, because currently many
people don't use devfs even though the kernel was compiled with
support for it. AFAIK, almost all other kernel modules register both
types. I have attached a patch that fixes this.
