From 433a87d528f685028b6f61fc3d7fae07ed915aa8 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Mon, 3 Jul 2006 12:02:27 -0400 Subject: [PATCH] [PATCH] ieee1394: skip dummy loop in build_speed_map The last loop in ieee1394 core's speed calculation is not required unless ieee1394.h::IEEE1394_SPEED_MAX is changed from its current value of 3.
