From bb6e093da23ace2724fdadd27738027468eb82b3 Mon Sep 17 00:00:00 2001 From: Florin Malita Date: Mon, 22 May 2006 22:35:30 -0700 Subject: [PATCH] orinoco: possible null pointer dereference in orinoco_rx_monitor() If the skb allocation fails, the current error path calls dev_kfree_skb_irq() with a NULL argument. Also, 'err' is not being used. Coverity CID: 275. Signed-off-by: Florin Malita Cc: "John W.
