Subject: [PATCH 1/2] eeepc-laptop: Fix user after free
Date: Mon, 4 Aug 2008 18:08:33 +0100	[thread overview]
Message-ID: <20080804170833.GA9513@srcf.ucam.org> (raw)

eeepc-laptop uses the hwmon struct after unregistering the device, 
causing an oops on module unload. Flip the ordering to fix.

Signed-off-by: Matthew Garrett <mjg@redhat.com>
