[PATCH] staging: ks7010: don't print skb->dev->name if skb is null

From: Colin King
Date: Mon Aug 15 2016 - 10:46:13 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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.
