There are some other Smatch warnings as well: drivers/net/usb/lan78xx.c:2302 lan78xx_start_xmit() error: we previously assumed 'skb' could be null (see line 2299) skb is dereferenced inside the function call. drivers/net/usb/lan78xx.c:2885 lan78xx_bh() info: ignoring unreachable code. drivers/net/usb/lan78xx.c:3159 lan78xx_probe() info: ignoring unreachable code. These are calls to BUG_ON(). You should just delete it, network drivers shouldn't call BUG_ON(), at most they should call WARN_ON(). regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
