Date: Wed, 14 Oct 2009 20:37:36 +0200 (CEST) From: Stefan Richter <stefanr@...6.in-berlin.de> To: linux1394-devel@...ts.sourceforge.net cc: linux-kernel@...r.kernel.org Subject: [PATCH 1/2] firewire: core: WARN on wrong usage of core transaction functions In the code path which creates request packets, clearly mark a switch branch which must never be reached with a WARN. In the code path which creates response packets, replace a BUG by a friendlier to debug WARN.
