From ca0c7453995d3696034435820522e2a60bd59bfc Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Thu, 2 Nov 2006 21:16:08 +0100 Subject: [PATCH] ieee1394: sbp2: clean up sbp2_ namespace Prepend sbp2*_ to anything globally defined in sbp2.c except for some macros. Strip sbp2_ from names of struct members.
