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().
