Subject: staging: ks7010: don't print skb->dev->name if skb is null
X-Git-Tag: v4.9-rc1~119^2~942
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=95d2a324660ac46420b64481507dcedab7341dad;p=karo-tx-linux.git

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.
