[PATCH 16/76] Char: merge ip2main and ip2base

[Alan Cox <alan@redhat.com>]

From: Jiri Slaby <jirislaby@gmail.com>

It's pretty useless to have one setup() function separated along with
module_init() which only calls a function from ip2main anyway. Get rid
of ip2base.

Remove also checks of always-true now.
