Subject: [PATCH] de2104x: remove BUG_ON() when changing media type
Date: Mon, 25 Feb 2008 18:45:46 +0100	[thread overview]
Message-ID: <200802251845.51562.linux@rainbow-software.org> (raw)
In-Reply-To: <20080225071505.GC26674@colo.lackof.org>

When the chip dies (probably because of a bug somewhere in the driver), 
de_stop_rxtx() fails and changing the media type crashes the whole machine. 
Replace BUG_ON() in de_set_media() with a warning.
