Message-ID: <Pine.LNX.4.64N.0610301659530.10486@attu3.cs.washington.edu> Date: Mon, 30 Oct 2006 17:01:07 -0800 (PST) From: David Rientjes <rientjes@...washington.edu> To: starvik@...s.com, dev-etrax@...s.com cc: linux-kernel@...r.kernel.org Subject: [PATCH] drivers cris: return on NULL dev_alloc_skb() If the next descriptor array entry cannot be allocated by dev_alloc_skb(), return immediately so it is not dereferenced later. We cannot register the device with a partial descriptor list.
