net/ethernet: ks8851_mll unregister_netdev() before freeing
We added another error condition here, but if we were to hit it then we need to unregister_netdev() before doing the free_netdev(). Otherwise we would hit the BUG_ON() in free_netdev(): BUG_ON(dev->reg_state != NETREG_UNREGISTERED); Signed-off-by: NDan Carpenter <dan.carpenter@oracle.com> Tested-by: NRaffaele Recalcati <raffaele.recalcati@bticino.it> Signed-off-by: NDavid S.
