net: lan78xx: Merge memcpy + lexx_to_cpus to get_unaligned_lexx
Merge the combo use of memcpy and lexx_to_cpus. Use get_unaligned_lexx instead. This simplifies the code. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Acked-by: Woojung Huh <woojung.huh@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
