Subject: [PATCH] dm9000: do not kfree() netdevice
Date: Mon, 12 Feb 2007 12:05:39 +0000 [thread overview]
Message-ID: <20070212120539.GA31390@fluff.org.uk> (raw)
The DM9000 network driver is calling kfree() on an netdev
causing the system to oops if the probe fails. The right
thing to do is call free_netdev().
Thanks to Russell King for spotting this.
