netdev: use const for some name functions
dev_change_name and netdev_drivername should use const char on parameters that are read-only input values. The strcpy to newname is not needed since newname is not used later in function. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
