From 6c88e475660edcd5571a5aab39ce8062183af951 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sun, 11 Mar 2007 22:47:34 +0100 Subject: ieee1394: remove unused csr1212 code Delete unused code. Make some extern functions static. Remove superfluous inline keywords. Move private definitions from csr1212.h to csr1212.c.
