Message-ID: <20070124114707.42370540@localhost.localdomain>
Date: Wed, 24 Jan 2007 11:47:07 +0000
From: Alan <alan@...rguk.ukuu.org.uk>
To: jgarzik@...ox.com, linux-kernel@...r.kernel.org
Subject: [PATCH]: set_mode, Fix the FIXME
When set_mode() changed ->set_mode didn't adapt. This makes the needed
changes and removes the relevant FIXME case.
