From 95d2a324660ac46420b64481507dcedab7341dad Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 15 Aug 2016 15:45:04 +0100 Subject: [PATCH] staging: ks7010: don't print skb->dev->name if skb is null A null pointer dereference will occur when skb is null and skb->dev->name is printed. Replace the skb->dev->name with plain text "ks_wlan" to fix this.
