From 6f061487f7d31427d7e8f420f366e5537ae16f43 Mon Sep 17 00:00:00 2001 From: Jay Fenlason Date: Wed, 27 Jun 2007 16:04:33 -0400 Subject: [PATCH] firewire: fw-sbp2: correctly dereference by container_of MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Replace a cast with a container_of(). As long as nobody reorders the structure elements, they do the same thing, but container_of() is more readable.
